Andrey Muchnik

Andrey Albertovich Muchnik (February 24, 1958 - March 18, 2007) was a Soviet and Russian mathematician who practiced mathematical logic.

Muchnik began working as a mathematician at the seminar of Evgenii Landis and Yulij Ilyashenko for third year students of the Faculty of Mechanics and Mathematics of Lomonosov Moscow State University.

Starting in his third year, he specialized in definability theory at the Department of Mathematical Logic, under the supervision of Alexei Semenov.

The problem involved eliminating transfinite induction in the proof of Rabin's theorem on the solvability of the monadic theory of infinite trees.

[2] Subsequently, he worked at the Institute of New Technologies and the Scientific Council of the USSR Academy of Sciences in the field of cybernetics[citation needed].
