Andrey Nikolayevich Tikhonov
Andrey Nikolayevich Tikhonov was a Soviet and Russian mathematician and geophysicist known for important contributions to topology, functional analysis, mathematical physics, ill-posed problems. He was one of the inventors of the magnetotellurics method in geophysics. Other transliterations of his surname include "Tychonoff", "Tychonov", "Tihonov", "Tichonov." Born near Smolensk, he studied at the Moscow State University where he received a Ph. D. in 1927 under the direction of Pavel Sergeevich Alexandrov. In 1933 he was appointed as a professor at Moscow State University, he became a corresponding member of the USSR Academy of Sciences on 29 January 1939 and a full member of the USSR Academy of Sciences on 1 July 1966. Tikhonov worked in a number of different fields in mathematics, he made important contributions to topology, functional analysis, mathematical physics, certain classes of ill-posed problems. Tikhonov regularization, one of the most used methods to solve ill-posed inverse problems, is named in his honor.
He is best known for his work on topology, including the metrization theorem he proved in 1926, the Tychonoff's theorem, which states that every product of arbitrarily many compact topological spaces is again compact. In his honor regular topological spaces are named Tychonoff spaces. In mathematical physics, he proved the fundamental uniqueness theorems for the heat equation and studied Volterra integral equations, he founded the theory of asymptotic analysis for differential equations with small parameter in the leading derivative. Tikhonov played the leading role in founding the Faculty of Computational Mathematics and Cybernetics of Moscow State University and served as its first dean during the period of 1970–1990. Tikhonov received numerous honors and awards for his work, including the Lenin Prize and the Hero of Socialist Labor. A. G. Sveshnikov, A. N.

Israel Moiseevich Gelfand written Israïl Moyseyovich Gel'fand, or Izrail M. Gelfand was a prominent Soviet mathematician, he made significant contributions to many branches of mathematics, including group theory, representation theory and functional analysis. The recipient of many awards, including the Order of Lenin and the Wolf Prize, he was a Fellow of the Royal Society and professor at Moscow State University and, after immigrating to the United States shortly before his 76th birthday, at Rutgers University, his legacy continues through his students, who include Endre Szemerédi, Alexandre Kirillov, Edward Frenkel, Joseph Bernstein, as well as his own son, Sergei Gelfand. A native of Kherson Governorate of the Russian Empire, Gelfand was born into a Jewish family in the small southern Ukrainian town of Okny. According to his own account, Gelfand was expelled from high school because his father had been a mill owner. Bypassing both high school and college, he proceeded to postgraduate study at the age of 19 at Moscow State University, where his advisor was the preeminent mathematician Andrei Kolmogorov.
Gelfand is known for many developments including: the book Calculus of Variations, which he co-authored with Sergei Fomin the Gelfand representation in Banach algebra theory. I. M. Gelfand's seminar at Moscow State University was running from 1945 until May 1989, covered a wide range of topics, was an important school for many mathematicians; the Gelfand–Tsetlin basis is a used tool in theoretical physics and the result of Gelfand's work on the representation theory of the unitary group and Lie groups in general. Gelfand published works on biology and medicine. For a long time he organized a research seminar on the subject, he worked extensively in mathematics education with correspondence education. In 1994, he was awarded a MacArthur Fellowship for this work. Gelfand was married to Zorya Shapiro, their two sons and Vladimir both live in the United States; the third son, died of leukemia. Following the divorce from his first wife, Gelfand married Tatiana; the family includes four grandchildren and three great-grandchildren.
The memories about I. Gelfand are collected at the special site handled by his family. Gelfand held several honorary degrees and was awarded the Order of Lenin three times for his research. In 1977 he was elected a Foreign Member of the Royal Society, he won the Wolf Prize in 1978, Kyoto Prize in 1989 and MacArthur Foundation Fellowship in 1994. He held the presidency of the Moscow Mathematical Society between 1968 and 1970, was elected a foreign member of the U. S. National Academy of Science, the American Academy of Arts and Sciences, the Royal Irish Academy, the American Mathematical Society and the London Mathematical Society. In an October 2003 article in The New York Times, written on the occasion of his 90th birthday, Gelfand is described as a scholar, considered "among the greatest mathematicians of the 20th century", having exerted a tremendous influence on the field both through his own works and those of his students. Israel Gelfand died at the Robert Wood Johnson University Hospital near his home in Highland Park, New Jersey.
He was less than five weeks past his 96th birthday. His death was first reported on the blog of his former collaborator Andrei Zelevinsky and confirmed a few hours by an obituary in the Russian online newspaper Polit.ru. Gelfand, I. M.

Moscow State University
Moscow State University is a coeducational and public research university located in Moscow, Russia. It was founded on 23 January 1755 by Mikhail Lomonosov. MSU was renamed after Lomonosov in 1940 and was known as Lomonosov University, it houses the tallest educational building in the world. Its current rector is Viktor Sadovnichiy. According to the 2018 QS World University Rankings, it is the highest-ranking Russian educational institution and is considered the most prestigious university in the former Soviet Union. Ivan Shuvalov and Mikhail Lomonosov promoted the idea of a university in Moscow, Russian Empress Elizabeth decreed its establishment on 23 January 1755; the first lectures were given on 7 May. Russians still celebrate 25 January as Students' Day. Saint Petersburg State University and Moscow State University engage in friendly rivalry over the title of Russia's oldest university. Though Moscow State University was founded in 1755, its competitor in St. Petersburg has had a continuous existence as a "university" since 1819 and sees itself as the successor of an academy established on 24 January 1724, by a decree of Peter the Great.
The present Moscow State University occupied the Principal Medicine Store on Red Square from 1755 to 1787. Catherine the Great transferred the University to a Neoclassical building on the other side of Mokhovaya Street. In the 18th century, the University had three departments: philosophy and law. A preparatory college was affiliated with the University until its abolition in 1812. In 1779, Mikhail Kheraskov founded a boarding school for noblemen which in 1830 became a gymnasium for the Russian nobility; the university press, run by Nikolay Novikov in the 1780s, published the most popular newspaper in Imperial Russia: Moskovskie Vedomosti. In 1804, medical education split into clinical and obstetrics faculties. During 1884–1897, the Department of Medicine—supported by private donations, the municipal and imperial governments—built an extensive, 1.6-kilometer-long, state-of-the-art medical campus in Devichye Pole, between the Garden Ring and Novodevichy Convent. The campus, medical education in general, were separated from the Moscow University in 1930.
Devichye Pole was operated by the independent I. M. Sechenov First Moscow State Medical University and by various other state and private institutions; the roots of student unrest in the University reach deep into the nineteenth century. In 1905, a social-democratic organization emerged at the University and called for the overthrow of the Czarist government and the establishment of a republic in Russia; the imperial government threatened to close the University. In 1911, in a protest over the introduction of troops onto the campus and mistreatment of certain professors, 130 scientists and professors resigned en masse, including such prominent men as Nikolay Dimitrievich Zelinskiy, Pyotr Nikolaevich Lebedev, Sergei Alekseevich Chaplygin. After the October Revolution of 1917, the institution began to admit the children of the proletariat and peasantry. In 1919, the University abolished fees for tuition and established a preparatory facility to help working-class children prepare for entrance examinations.
During the implementation of Joseph Stalin's first five-year plan, prisoners from the Gulag were forced to construct parts of the newly expanded University. After 1991, nine new faculties were established; the following year, the University gained a unique status: it is funded directly from the state budget, thus providing the University a significant level of independence. On 6 September 1997, the French electronic musician Jean Michel Jarre, whom the mayor of Moscow had specially invited to perform, used the entire front facade of the University as the backdrop for a concert: the frontage served as a giant projection screen, with fireworks and searchlights all launched from various points around the building; the stage stood directly in front of the building, the concert, entitled "The Road To The 21st Century" in Russia but renamed "Oxygen In Moscow" for worldwide release in video/DVD, attracted a world-record crowd of 3.5 million people. On 19 March 2008, Russia's most powerful supercomputer to date, the SKIF MSU was launched at the University.
Its peak performance of 60 TFLOPS makes it the fastest supercomputer in the Commonwealth of Independent States. Since 1953, most of the faculties have been situated on Sparrow Hills, in the southwest of Moscow, 5 km from the city centre; the main building was designed by architect Lev Vladimirovich Rudnev. In the post-war era, Joseph Stalin ordered seven huge tiered neoclassic towers to be built around the city, it was built using Gulag labour. Located on Moscow's outskirts at the time of its construction, the location of the main building is now about half-way between the center of Moscow a
The Soviet Union the Union of Soviet Socialist Republics, was a socialist state in Eurasia that existed from 1922 to 1991. Nominally a union of multiple national Soviet republics, its government and economy were centralized; the country was a one-party state, governed by the Communist Party with Moscow as its capital in its largest republic, the Russian Soviet Federative Socialist Republic. Other major urban centres were Leningrad, Minsk, Alma-Ata, Novosibirsk, it spanned over 10,000 kilometres east to west across 11 time zones, over 7,200 kilometres north to south. It had five climate zones: tundra, steppes and mountains; the Soviet Union had its roots in the 1917 October Revolution, when the Bolsheviks, led by Vladimir Lenin, overthrew the Russian Provisional Government which had replaced Tsar Nicholas II during World War I. In 1922, the Soviet Union was formed by a treaty which legalized the unification of the Russian, Transcaucasian and Byelorussian republics that had occurred from 1918. Following Lenin's death in 1924 and a brief power struggle, Joseph Stalin came to power in the mid-1920s.
Stalin committed the state's ideology to Marxism–Leninism and constructed a command economy which led to a period of rapid industrialization and collectivization. During his rule, political paranoia fermented and the Great Purge removed Stalin's opponents within and outside of the party via arbitrary arrests and persecutions of many people, resulting in at least 600,000 deaths. In 1933, a major famine struck the country. Before the start of World War II in 1939, the Soviets signed the Molotov–Ribbentrop Pact, agreeing to non-aggression with Nazi Germany, after which the USSR invaded Poland on 17 September 1939. In June 1941, Germany broke the pact and invaded the Soviet Union, opening the largest and bloodiest theatre of war in history. Soviet war casualties accounted for the highest proportion of the conflict in the effort of acquiring the upper hand over Axis forces at intense battles such as Stalingrad and Kursk; the territories overtaken by the Red Army became satellite states of the Soviet Union.
The post-war division of Europe into capitalist and communist halves would lead to increased tensions with the United States-led Western Bloc, known as the Cold War. Stalin died in 1953 and was succeeded by Nikita Khrushchev, who in 1956 denounced Stalin and began the de-Stalinization; the Cuban Missile Crisis occurred during Khrushchev's rule, among the many factors that led to his downfall in 1964. In the early 1970s, there was a brief détente of relations with the United States, but tensions resumed with the Soviet–Afghan War in 1979. In 1985, the last Soviet premier, Mikhail Gorbachev, sought to reform and liberalize the economy through his policies of glasnost and perestroika, which caused political instability. In 1989, Soviet satellite states in Eastern Europe overthrew their respective communist governments; as part of an attempt to prevent the country's dissolution due to rising nationalist and separatist movements, a referendum was held in March 1991, boycotted by some republics, that resulted in a majority of participating citizens voting in favor of preserving the union as a renewed federation.
Gorbachev's power was diminished after Russian President Boris Yeltsin's high-profile role in facing down a coup d'état attempted by Communist Party hardliners. In late 1991, Gorbachev resigned and the Supreme Soviet of the Soviet Union met and formally dissolved the Soviet Union; the remaining 12 constituent republics emerged as independent post-Soviet states, with the Russian Federation—formerly the Russian SFSR—assuming the Soviet Union's rights and obligations and being recognized as the successor state. The Soviet Union was a powerhouse of many significant technological achievements and innovations of the 20th century, including the world's first human-made satellite, the first humans in space and the first probe to land on another planet, Venus; the country had the largest standing military in the world. The Soviet Union was recognized as one of the five nuclear weapons states and possessed the largest stockpile of weapons of mass destruction, it was a founding permanent member of the United Nations Security Council as well as a member of the Organization for Security and Co-operation in Europe, the World Federation of Trade Unions and the leading member of the Council for Mutual Economic Assistance and the Warsaw Pact.
The word "Soviet" is derived from a Russian word сове́т meaning council, advice, harmony and all deriving from the proto-Slavic verbal stem of vět-iti, related to Slavic věst, English "wise", the root in "ad-vis-or", or the Dutch weten. The word sovietnik means "councillor". A number of organizations in Russian history were called "council". For example, in the Russian Empire the State Council, which functioned from 1810 to 1917, was referred to as a Council of Ministers after the revolt of 1905. During the Georgian Affair, Vladimir Lenin envisioned an expression of Great Russian ethnic chauvinism by Joseph Stalin and his supporters, calling for these nation-states to join Russia as semi-independent parts of a greater union, which he named as the Union of Soviet Republics of Europe and Asia. Stalin resisted the proposal, but accepted it, although with Lenin's agreement changed the name of the newly proposed sta
Vladivostok is a city and the administrative center of Far Eastern Federal District and Primorsky Krai, located around the Golden Horn Bay, not far from Russia's borders with China and North Korea. The population of the city as of 2017 was 606,589, up from 592,034 recorded in the 2010 Russian census. Harbin in China is about 515 kilometres away, whilst Sapporo in Japan is about 775 kilometres east across the Sea of Japan; the city is the home port of the Russian Pacific Fleet and the largest Russian port on the Pacific Ocean. Vladivostok was first named in 1859 along with other features in the Peter the Great Gulf area by Nikolay Muravyov-Amursky; the name first applied to the bay but, following an expedition by Alexey Shefner in 1860, was applied to the new settlement. In Chinese, the place where the city is situated nowadays has been known since the Qing Dynasty as Haishenwai, from the Manchu Haišenwai or "small seaside village"; as the Manchu Qing Dynasty banned Han Chinese from most of Manchuria, it was only visited by shēnzéi who illegally entered the area seeking ginseng or sea cucumbers.
From this comes the Chinese name for the city, Hǎishēnwǎi. In modern-day China, Vladivostok is known by the transliteration 符拉迪沃斯托克, although the historical Chinese name 海參崴 is still used in common parlance and outside mainland China to refer to the city. According to the provisions of the Chinese government, all maps published in China have to bracket the city's Chinese name; the modern-day Japanese name of the city is transliterated as Urajiosutoku. The city was written in Kanji as 浦塩斯徳 and shortened to Urajio ウラジオ. In Korean, the name is transliterated as Beulladiboseutokeu in South Korea, Ullajibosŭttokhŭ in North Korea and China; the aboriginals of the territory on which modern Vladivostok is located are the Udege minority, a sub-minority called the Taz which emerged through members of the indigenous Udege mixing with the nearby Chinese and Hezhe. The region had been part of many states, such as the Mohe, Balhae Kingdom, Liao Dynasty, Jīn Dynasty, Yuan Dynasty, Ming Dynasty, Qing Dynasty and various other Chinese dynasties, before Russia acquired the entire Maritime Province and the island of Sakhalin by the Treaty of Beijing.
Qing China, which had just lost the Opium War with Britain, was unable to defend the region. The Manchu emperors of China, the Qing Dynasty, banned Han Chinese from most of Manchuria including the Vladivostok area —it was only visited by illegal gatherers of ginseng and sea cucumbers. On June 20, 1860, the military supply ship Manchur, under the command of Captain-Lieutenant Alexey K. Shefner, called at the Golden Horn Bay to found an outpost called Vladivostok. Warrant officer Nikolay Komarov with 28 soldiers and two non-commissioned officers under his command were brought from Nikolayevsk-on-Amur by ship to construct the first buildings of the future city; the Manza War in 1868 was the first attempt by Russia to expel Chinese from territory. Hostilities broke out around Vladivostok when the Russians tried to shut off gold mining operations and expel Chinese workers there; the Chinese resisted a Russian attempt to take Ashold Island and in response, two Russian military stations and three Russian towns were attacked by the Chinese whom the Russians failed to oust.
An elaborate system of fortifications was erected between the late 1890s. A telegraph line from Vladivostok to Shanghai and Nagasaki was opened in 1871; that same year a commercial port was relocated to Vladivostok from Nikolayevsk-on-Amur. Town status was granted on April 22, 1880. A coat of arms, representing the Siberian tiger, was adopted in March 1883; the first high school was opened in 1899. The city's economy was given a boost in 1916, with the completion of the Trans-Siberian Railway, which connected Vladivostok to Moscow and Europe. After the October Revolution, the Bolsheviks took control of Vladivostok and all the Trans-Siberian Railway. During the Russian Civil War they were overthrown by the White-allied Czechoslovak Legion, who declared the city to be an Allied protectorate. Vladivostok became the staging point for the Allies' Siberian intervention, a multi-national force including Japan, the United States, China; the intervention ended in the wake of the collapse of the White Army and regime in 1919.
In April 1920, the city came under the formal governance of the Far Eastern Republic, a Soviet-backed buffer state between the Soviets and Japan. Vladivostok became the capital of the Japanese-backed Provisional Priamurye Government, created after a White Army coup in the city in May 1921; the withdrawal of Japanese forces in October 1922 spelled the end of the enclave, with Ieronim Uborevich's Red Army taking the city on October 25, 1922. As the main naval base of the Soviet Pacific Fleet, Vladivostok was closed to foreigners during the Soviet years; the city hosted the summit at which Leonid Brezhnev and Gerald Ford conducted the Strategic Arms Limitation Talks in 1974. At the time, the two countries decided quantitative limits on nuclear weapons systems and banned the construction of new land-based ICBM launchers. In 2012, Vladivostok hosted the 24th APEC s
Virtual International Authority File
The Virtual International Authority File is an international authority file. It is a joint project of several national libraries and operated by the Online Computer Library Center. Discussion about having a common international authority started in the late 1990s. After a series of failed attempts to come up with a unique common authority file, the new idea was to link existing national authorities; this would present all the benefits of a common file without requiring a large investment of time and expense in the process. The project was initiated by the US Library of Congress, the German National Library and the OCLC on August 6, 2003; the Bibliothèque nationale de France joined the project on October 5, 2007. The project transitioned to being a service of the OCLC on April 4, 2012; the aim is to link the national authority files to a single virtual authority file. In this file, identical records from the different data sets are linked together. A VIAF record receives a standard data number, contains the primary "see" and "see also" records from the original records, refers to the original authority records.
The data are available for research and data exchange and sharing. Reciprocal updating uses the Open Archives Initiative Protocol for Metadata Harvesting protocol; the file numbers are being added to Wikipedia biographical articles and are incorporated into Wikidata. VIAF's clustering algorithm is run every month; as more data are added from participating libraries, clusters of authority records may coalesce or split, leading to some fluctuation in the VIAF identifier of certain authority records.

National Library of the Czech Republic
The National Library of the Czech Republic is the central library of the Czech Republic. It is directed by the Ministry of Culture; the library's main building is located in the historical Clementinum building in Prague, where half of its books are kept. The other half of the collection is stored in the district of Hostivař; the National Library is the biggest library in the Czech Republic, in its funds there are around 6 million documents. The library has around 60,000 registered readers; as well as Czech texts, the library stores older material from Turkey and India. The library houses books for Charles University in Prague; the library won international recognition in 2005 as it received the inaugural Jikji Prize from UNESCO via the Memory of the World Programme for its efforts in digitising old texts. The project, which commenced in 1992, involved the digitisation of 1,700 documents in its first 13 years; the most precious medieval manuscripts preserved in the National Library are the Codex Vyssegradensis and the Passional of Abbes Kunigunde.
In 2006 the Czech parliament approved funding for the construction of a new library building on Letna plain, between Hradčanská metro station and Sparta Prague's football ground, Letná stadium. In March 2007, following a request for tender, Czech architect Jan Kaplický was selected by a jury to undertake the project, with a projected completion date of 2011. In 2007 the project was delayed following objections regarding its proposed location from government officials including Prague Mayor Pavel Bém and President Václav Klaus. Plans for the building had still not been decided in February 2008, with the matter being referred to the Office for the Protection of Competition in order to determine if the tender had been won fairly. In 2008, Minister of Culture Václav Jehlička announced the end of the project, following a ruling from the European Commission that the tender process had not been carried out legally; the library was affected by the 2002 European floods, with some documents moved to upper levels to avoid the excess water.
Over 4,000 books were removed from the library in July 2011 following flooding in parts of the main building. There was a fire at the library in December 2012. List of national and state libraries Official website
