Arkady L'vovich Onishchik (Russian: Арка́дий Льво́вич Они́щик, born 14 November 1933[1] in Moscow; died 12 February 2019[2]) was a prominent Soviet and Russian mathematician, who worked on Lie groups and their geometrical applications. Onishchik was a student of Eugene Dynkin,[3] under whose guidance he got his PhD at Moscow State University in 1960.[1] In 1962 Onishchik received the Prize of the Moscow Mathematical Society for young mathematicians.[4] In 1970 he got Habilitation (Russian title of Doctor of Sciences).[1] Since 1975 Onishchik was a professor of Yaroslavl State University.[2]

Onishchik introduced new homotopy invariants of homogeneous spaces and classified factorizations of connected simple compact Lie groups into the product of two connected Lie subgroups.[1] In complex analysis, the Matsushima–Onishchik theorem describes homogeneous spaces of complex reductive groups that are Stein manifolds.[1] In addition to Lie groups and algebras, Onishchik also worked on nonabelian cohomology and on supermanifolds.[2]
