Cyclic group

In group theory, a branch of abstract algebra, a cyclic group or monogenous group is a group, generated by a single element. That is, it is a set of invertible elements with a single associative binary operation, it contains an element g such that every other element of the group may be obtained by applying the group operation to g or its inverse; each element can be written as a power of g in multiplicative notation, or as a multiple of g in additive notation. This element g is called a generator of the group; every infinite cyclic group is isomorphic to the additive group of the integers. Every finite cyclic group of order n is isomorphic to the additive group of Z/nZ, the integers modulo n; every cyclic group is an abelian group, every finitely generated abelian group is a direct product of cyclic groups. Every cyclic group of prime order is a simple group. In the classification of finite simple groups, one of the three infinite classes consists of the cyclic groups of prime order; the cyclic groups of prime order are thus among the building blocks from which all groups can be built.

For any element g in any group G, one can form the subgroup of all integer powers ⟨g⟩ =, called the cyclic subgroup of g. The order of g is the number of elements in ⟨g⟩. A cyclic group is a group, equal to one of its cyclic subgroups: G = ⟨g⟩ for some element g, called a generator. For a finite cyclic group G of order n we have G =, where e is the identity element and gi = gj whenever i ≡ j. An abstract group defined by this multiplication is denoted Cn, we say that G is isomorphic to the standard cyclic group Cn; such a group is isomorphic to Z/nZ, the group of integers modulo n with the addition operation, the standard cyclic group in additive notation. Under the isomorphism χ defined by χ = i the identity element e corresponds to 0, products correspond to sums, powers correspond to multiples. For example, the set of complex 6th roots of unity G = forms a group under multiplication, it is cyclic, since it is generated by the primitive root z = 1 2 + 3 2 i = e 2 π i / 6: that is, G = ⟨z⟩ = with z6 = 1.

Under a change of letters, this is isomorphic to the standard cyclic group of order 6, defined as C6 = ⟨g⟩ = with multiplication gj · gk = gj+k, so that g6 = g0 = e. These groups are isomorphic to Z/6Z = with the operation of addition modulo 6, with zk and gk corresponding to k. For example, 1 + 2 ≡ 3 corresponds to z1 · z2 = z3, 2 + 5 ≡ 1 corresponds to z2 · z5 = z7 = z1, so on. Any element generates its own cyclic subgroup, such as ⟨z2⟩ = of order 3, isomorphic to C3 and Z/3Z. Instead of the quotient notations Z/nZ, Z/, or Z/n, some authors denote a finite cyclic group as Zn, but this conflicts with the notation of number theory, where Zp denotes a p-adic number ring, or localization at a prime ideal. On the other hand, in an infinite cyclic group G = ⟨g⟩, the powers gk give distinct elements for all integers k, so that G =, G is isomorphic to the standard group C = C∞ and to Z, the additive group of the integers. An example is the first frieze group. Here there are no finite cycles, the name "cyclic" may be misleading.

To avoid this confusion, Bourbaki introduced the term monogenous group for a group with a single generator and restricted "cyclic group" to mean a finite monogenous group, avoiding the term "infinite cyclic group". The set of integers Z, with the operation of addition, forms a group, it is an infinite cyclic group, because all integers can be written by adding or subtracting the single number 1. In this group, 1 and −1 are the only generators; every infinite cyclic group is isomorphic to Z. For every positive integer n, the set of integers modulo n, again with the operation of addition, forms a finite cyclic group, denoted Z/nZ. A modular integer i is a generator of this group if i is prime to n, because these elements can generate all other elements of the group through integer addition; every finite cyclic group G is isomorphic to Z/nZ. The addition operations on integers and modular integers, used to define the cyclic groups, are the addition operations of commutative rings denoted Z and Z/nZ or Z/.

If p is a prime Z/pZ is a finite field, is denoted Fp or GF. Fo

2009 VFL season

The 2009 Victorian Football League season was the 128th season of the Australian Rules Football competition. The premiership was won by the North Ballarat Football Club, which defeated the Northern Bullants by 23 points in the Grand Final on 25 September, it was North Ballarat's second consecutive premiership, the second in the club's history. At the end of the 2008 season, the Tasmanian Devils Football Club withdrew from the VFL and disbanded. AFL Tasmania, which operated the club, was focussed on re-establishing the Tasmanian Football League as a statewide competition in 2009, after an eight-year hiatus since the original statewide league's collapse at the end of 2000, having the Tasmanian VFL club competing for attention and players did not fit with this vision; as a result, the VFL was reduced to thirteen clubs. Additionally, two pairs of VFL-AFL reserves affiliations were altered: Melbourne ended its nine-year affiliation with Sandringham and entered a new affiliation with the Casey Scorpions.

St Kilda ended its eight-year affiliation with the Casey Scorpions and entered a new affiliation with Sandringham. As a result, the size of the VFL was reduced to thirteen teams: nine VFL-AFL affiliates, two AFL reserves team, two stand-alone VFL teams; the Jim'Frosty' Miller Medal was won by Nick Sautner for the ninth time in his career. Sautner kicked 71 goals for the season; the J. J. Liston Trophy was by Myles Sewell. Sewell finished ahead of Michael Barlow, second with 16 votes, James Podsiadly and Sam Iles, who were equal third with 15 votes; the Fothergill-Round Medal was won by Michael Barlow. Box Hill won the reserves premiership. Box Hill 16.18 defeated Sandringham 13.6 in the Grand Final, held as a curtain-raiser to the seniors second preliminary final on 20 September. The Bendigo Bombers could not play at their home ground Queen Elizabeth Oval after May because the surface was deemed unfit for VFL football. Bendigo's remaining home games were transferred to Windy Hill, the training ground of its AFL-affiliate Essendon.

The VFL introduced the "23rd man rule". Under the rule, the size of the playing squad was increased to twenty-three, provided the 23rd player was a top-age player in the TAC Cup, or an undrafted player who had played in the TAC Cup during the previous year; the rule was designed to provide additional senior football opportunities to promising juniors, improve the alignments between VFL clubs and their TAC Cup affiliates.

Gwen Davis

Gwen Davis is an American novelist, screenwriter, songwriter and poet. Davis has written eighteen novels, including the sexy bestseller The Pretenders, she has written about travel for the Wall Street Journal Europe, for online publications such as the Huffington Post, maintains a popular personal blog, Report from the Front, a blog reviewing Broadway theater productions, Will Blog for Broadway. Davis was born in Pittsburgh and grew up in New York City, in Manhattan, her parents were divorced. Her father, real estate developer Lew Davis served as mayor of Tucson, winning office in 1961, her parents' separation when she was five started a lifetime of gypsying. She attended Bryn Mawr College. In 1954, at the age of eighteen, she went to Paris to study music and sang in a nightclub there until she gave into her mother's pleas to return to the U. S, she moved to continued singing, performing at the Purple Onion. She obtained a master's degree in Creative Writing from Stanford University, she was part of the Hollywood social scene from the late 1950s, coming into contact with a wide range of celebrities and befriending Dennis Hopper and many others.

Some of her experiences inspired Naked in Babylon. She married businessman and producer Don Mitchell, with whom she had two children, a daughter and a son. One of the Mitchells' mocking Academy Awards parties was the subject of a Time magazine article in 1970, which mentioned some of the celebrities—Shirley MacLaine, Zsa Zsa Gabor, Lee Marvin and others—Davis and Mitchell counted among their friends, she scripted a famous movie, What a Way to Go, wrote a play produced on Broadway, The Best Laid Plans. Davis continues to write, she travels and has lived in Spain, Rome, Venice, New York and Hollywood. She has returned from living in Bali, Indonesia and is living between New York, Beverly Hills. Touching was not a bestselling novel. Davis spent twenty hours at Sandstone, a Topanga Canyon therapy center run by E. Paul Bindrim, known as the "father of Nude Psychotherapy". Bindrim, once nearly kicked out of the American Psychological Association, was known for holding what he called "nude marathons"—several clients were "placed in a warm pool for long sessions of touching and massaging and sometimes shouting or acting out rage".

After the novel was published, Bindrim sued Davis and Doubleday & Company for libel, on the grounds that it had defamed him. Davis claimed she had used her real-life experiences to inspire fiction, but that Bindrim was not the psychologist in her fictional story, did not resemble him—the character she depicted was overweight, looked like Santa Claus, had a Ph. D; when the case came to trial, bald and clean shaven, who held only a master's degree, had by gained weight, grown a white beard, been granted a Ph. D. from International College in Westwood, California. These changes made, he won his lawsuit against her publisher, Doubleday. Doubleday sued Davis for not disclosing her contractual agreement with Bindrim not to write about the psychotherapy event; because of the Bindrin precedent, American novelists in America became concerned about the possibility of lawsuits against writers who used real people as the basis for their fiction. Davis settled the lawsuit for an undisclosed amount.
