José Ádem (born in Tuxpan, Veracruz, October 27, 1921; died February 14, 1991) was a Mexican mathematician who worked in algebraic topology, and proved the Ádem relations between Steenrod squares.

Life and education[edit]

Ádem showed an interest in mathematics from an early age, and moved to Mexico City in 1941 to pursue a degree in engineering and mathematics. He obtained his B.S. in mathematics from the National Autonomous University of Mexico (UNAM) in 1949.[1] During this time met Solomon Lefschetz, a famous algebraic topologist who was spending prolonged periods of time in Mexico. Lefschetz recognized Ádem's mathematical talent, and sent him as a doctoral student to Princeton University where he graduated in 1952.[2] His dissertation, Iterations of the squaring operations in algebraic topology, was written under the supervision of Norman Steenrod and introduced what are now called the Ádem relations.[3]

His brother Julián Adem was also a distinguished Mexican mathematician, who obtained a Ph.D. in applied mathematics from Brown University in 1953.[4] Julián's son is topologist Alejandro Adem.[5]

Career[edit]

Ádem became a researcher at the Mathematics Institute of UNAM (1954–1961), and then head of the Mathematics Department at the Instituto Politécnico Nacional (1961–1973).[6] He was elected to El Colegio Nacional on 4 April 1960.[1]

In 1951 he was awarded a Guggenheim Fellowship.[7] He started in 1956 the second series of the Boletín de la Sociedad Matemática Mexicana.[2]
