Gennady Feldman

Gennadiy Mykhailovych Feldman (; born October 15, 1947, Kharkiv) is a Soviet and Ukrainian mathematician, corresponding member of the National Academy of Sciences of Ukraine , Doctor of Science in Physics and Mathematics, Professor, Head of the Mathematical Division of B. Verkin Institute for Low Temperature Physics and Engineering of the National Academy of Sciences of Ukraine. Biography In 1970, Feldman graduated in the Faculty of Mechanics and Mathematics of V. N. Karazin Kharkiv National University. From 1970 to 1973, he was a PhD student at B. Verkin Institute for Low Temperature Physics and Engineering. In 1973, he defended his thesis Harmonic Analysis of Non-unitary Representations of Locally Compact Abelian Groups (supervisor Prof. Yu. I. Lyubich ) and obtained the degree of Candidate of Sciences (PhD). He has been working at B. Verkin Institute for Low Temperature Physics and Engineering, starting as a junior researcher and heading the Mathematical Division in 2012. In 1985, he defended his doctoral thesis, Arithmetic of Probability Measures on Locally Compact Abelian groups at Vilnius University and obtained the degree of Doctor of Sciences (Dr. Hab.). In 2018, he was elected as a corresponding member of the National Academy of Sciences of Ukraine. For more than 20 years, Feldman worked part-time at the Faculty of Mechanics and Mathematics of V. N. Karazin Kharkiv National University. He is the author of 5 monographs and more than 100 scientific articles. Research Feldman’s research interests are related to abstract harmonic analysis and the algebraic theory of probability. He obtained fundamental results in the theory of decompositions of random variables on locally compact Abelian groups. Before the beginning of his research in this field, only a few isolated works existed. In particular, Feldman proved group analogues of Cramér’s theorem on the decomposition of Gaussian distributions and of Linnik’s theorem on the decomposition of convolutions of Gaussian and Poisson distributions (jointly with A. E. Fryntov). He proved analogues of the classical characterization theorems of mathematical statistics (Kac–Bernstein theorem, Darmois–Skitovich theorem, Heyde theorem) in the case where random variables take values in various classes of locally compact Abelian groups (discrete, compact totally disconnected, the field of p-adic numbers, and others).
