Here we give the biographical background and discuss his well known researches in different areas of science and technology.
Evgeniy Vladimirovich Radkevich began his mathematical education in Moscow State University, Faculty of Mechanics and Mathematics. He has studied under Olga Arsenievna Oleinik, a famous mathematician, one of the best specialists in the theory of partial differential equations, and has become a Candidate of Physical and Mathematical Sciences. E. V. Radkevich worked in the leading mathematical institutes—Institute for Problems in Mechanics of the USSR Academy of Sciences, Moscow Institute of Electronics and Mathematics, Moscow Institute of Radio-Engineering, Electronics and Automation, Moscow State University.
Now he is Professor, Doctor habilitated of Physical and Mathematical Sciences, his interests are in many areas of mathematics (differential equations and boundary value problems, asymptotical methods, phase transition problems and so on) and also he is an experienced teacher and lecturer.
In the paper we give a list of Evgeniy Vladimirovich publications for the last five years to show the level of his scientific researches. Also here we discuss his greatest scientific and technological contributions and concern the other important area of interest of E. V. Radkevich—the theatre arts, and his work as theatre director.
