# Ivan Petrovsky

Ivan Georgievich Petrovsky, also Petrovskii (Russian: Ива́н Гео́ргиевич Петро́вский) (18 January 1901, Sevsk – 15 January 1973, Moscow) was a Soviet mathematician in the field of partial differential equations, and studied Petrovsky lacunas. He greatly contributed to solution of Hilbert's 19-th and 16th problems. He also worked on the boundary value problem, probability, and topology of algebraic curves and surfaces.

Petrovsky was a student of Dmitri Egorov. Among his students were Olga Ladyzhenskaya, Yevgeniy Landis, Olga Oleinik and Sergei Godunov.

Petrovsky taught at Steklov Institute of Mathematics. He was a member of the Soviet Academy of Sciences since 1946 and was awarded Hero of Socialist Labor in 1969. He was the president of Moscow State University (1951 — 1973) and the head of the International Congress of Mathematicians (Moscow, 1966).
