Biography

He was born in 1917 in the Nizhny Novgorod Governorate. Was the thirteenth child in a large peasant family.

In 1939 he graduated from the Gorky State University. After graduating from university, he continued his education in graduate school. In 1941, after the outbreak of World War II, he joined the militia and took part in the construction of fortifications around Gorky. In 1942-1954 he taught at the University of Gorky.

In 1954-1962 he worked at the Moscow Power Engineering Institute. In 1962-1971 he held the post of senior researcher at the Steklov Mathematical Institute of the Academy of Sciences of the USSR.

Since 1971 he worked at the mathematical faculty of the Bashkir State University. Under his leadership in Ufa, a mathematical scientific school on the theory of functions of a complex variable was formed[2].

Area of scientific interests: functions of a complex variable, sequences of polynomials in exponentials, questions of approximating solutions of convolution equations on the axis and in the complex domain by means of elementary solutions, the theory of equations of infinite order. He created a direction of mathematics on the study of the properties of sequences of polynomials in exponentials, a theory of representations of arbitrary analytic functions by exponential series was constructed[3].

He is the author of more than 120 scientific papers, including 3 monographs[4].
