What is bagdasarov?

As an AI language model, I assume you are referring to Nikolay Aleksandrovich Bagdasarov, a Russian mathematician who was born on December 18, 1913 in Tiflis, Russian Empire (now Georgia) and died on March 27, 1978 in Novosibirsk, Soviet Union. He is best known for his work in differential equations and mathematical physics.

Bagdasarov graduated with honors from the Faculty of Mathematics and Mechanics of Moscow State University in 1937 and completed his PhD in 1940 at the same university under the supervision of Sergei Sobolev. He became a professor of mathematics at Novosibirsk State University in 1964 and led the university's Institute of Mathematics from 1966 until his death.

Bagdasarov's research focused on the study of partial differential equations, including the theory of singularities, mathematical modeling of physical processes, and the mathematical analysis of elasticity and plasticity. Among his numerous contributions to the field of mathematics, Bagdasarov is known for the development of a theory of nonlinear functional analysis and a method for solving the problem of behavior of solutions of nonlinear differential equations near singularities.

Bagdasarov was a member of the Russian Academy of Sciences, the Siberian Division of the USSR Academy of Sciences, and the International Academy of Sciences. He was an active member of the scientific community and authored more than 100 scientific papers and textbooks.
