Which of the following is known for his work on the decidability of algebraic groups: Anatoly Maltsev or Vladimir Levenshtein?
Vladimir Levenshtein Vladimir Iosifovich Levenshtein (Russian: Влади́мир Ио́сифович Левенште́йн ; ] ; born 1935) is a Russian scientist who has done research in information theory, error-correcting codes, and combinatorial design. Among other contributions, he is known for the Levenshtein distance and a Levenshtein algorithm, which he developed in 1965.
Sergey Yablonsky Sergey Vsevolodovich Yablonsky (Russian: Серге́й Все́володович Ябло́нский, 6 December 1924 – 26 May 1998) was a Soviet and Russian mathematician, one of the founders of the Soviet school of mathematical cybernetics and discrete mathematics. He is the author of a number of classic results on synthesis, reliability, and classification of control systems (Russian: Управляющие системы ), the term used in the USSR and Russia for a generalization of finite state automata, Boolean circuits and multi-valued logic circuits. (The term is ambiguous, since conventionally in the West control systems is understood as an engineering discipline. The ambiguity stems from the fact that the names of the two disciplines that differ in Russian, namely "Системы управления" and "Управляющие системы", are both translated into English as "control systems".)
