Which of the following is known for his work on the decidability of algebraic groups: Anatoly Maltsev or Vladimir Levenshtein?
Anatoly Maltsev Anatoly Ivanovich Maltsev (also: Malcev, Mal'cev; Russian: Анато́лий Ива́нович Ма́льцев; 27 November N.S./14 November O.S. 1909, Moscow Governorate – 7 June 1967, Novosibirsk) was born in Misheronsky, near Moscow, and died in Novosibirsk, USSR. He was a mathematician noted for his work on the decidability of various algebraic groups. Malcev algebras (generalisations of Lie algebras) are named after him.
Ivan Ivanovich Zhegalkin Ivan Ivanovich Zhegalkin (Russian Ива́н Ива́нович Жега́лкин; alternative romanizations: Žegalkin, Gégalkine) (August 3, 1869, Mtsensk – March 28, 1947, Moscow) was a Russian mathematician. He is best known for his formulation of Boolean algebra as the theory of the ring of integers mod 2, via what are now called Zhegalkin polynomials.
