Russian-Soviet mathematician (1938–2018)
Yurii (or Yuri) Vladimirovich Egorov (Юрий Владимирович Егоров, 14 July 1938 – October 2018) was a Russian-Soviet mathematician who specialized in differential equations.
Biography.
In 1960 he completed his undergraduate studies at the Mechanics and Mathematics Faculty of Moscow State University (MSU). In 1963 from MSU he received his Ph.D. with the thesis "Некоторые задачи теории оптимального управления в бесконечномерных пространствах" ("Some Problems of Optimal Control Theory in Infinite-Dimensional Spaces"). In 1970 from MSU he received his Russian doctorate of sciences (Doctor Nauk) with thesis: "О локальных свойствах псевдодифференциальных операторов главного типа" ("Local Properties of Pseudodifferential Operators of Principal Type"). He was employed at MSU from 1961 to 1992, and he was a full professor in the Department of Differential Equations of the Mechanics and Mathematics Faculty there from 1973 to 1992. Since 1992 he has been a professor of mathematics at Paul Sabatier University (Toulouse III).
Egorov's research deals with differential equations and applications in mathematical physics, spectral theory, and optimal control theory. In 1970 he was an Invited Speaker of the ICM in Nice.
