Volodymyr Vasylovych Kyrychenko

Abstract

The paper is dedicated to the memory of an outstanding ukrainian mathematician and teacher, one of the founders of Kyiv school of representation theory and ring theory, professor of Taras Shevchenko National University of Kyiv Volodymyr Vasylovych Kyrychenko. Volodymyr Vasylovych was born in 1942 in Penza. He graduated Kyiv University with honors in 1964. He defended his PhD thesis “Representations of hereditary, completely decomposable and Bass orders” under the supervision of D.K. Faddeev. He defended his habilitation “Modules and structural theory of rings” in 1986. He started to work at Kyiv University as an assistant of the Algebra and Mathematical Logic Department in 1967. Since then he served as an Associate Professor and Professor of the Algebra and Mathematical Logic Department. He was the head of the Geometry Department from 1988 till 2016. His main scientific results lay in the field of structural ring theory. In particular, he introduced the notion of the quiver for some special casses of rings and developed the structural theory of hereditary semiserial semidistributive rings. He is the author of about 250 scientific papers and 5 fundamental monographies. In his monographies the theory of semiperfect rings is presented by means of correspond- ing quivers. The monography “Finite dimensional algebras” written jointly with professor Y. Drozd is regarded one of the classical works in algebra and translated from Russian to Chineese, English and Spanish. He was an outstanding teacher and 36 PhD thesis were defended under his supervision. His lectures on analytical geometry and ring theory were always top ranked among students. Professor Kyrychenko was one of the founders of the journal “Algebra and Discrete Mathematics”. He was an editor of a couple of mathematical journals. In 1997 he was one of the founders of the series of international algebraic conferences in Ukraine that were conducted every two years. Since that he was one of the main organizers of each of them.
