Oleg Janowitsch Wiro , Russian Олег Янович Виро (born May 13, 1948 in Leningrad ) is a Russian mathematician who deals with topology and real algebraic geometry.

Life

Wiro received his doctorate (candidate title) in 1974 from the University of Leningrad under Vladimir Abramowitsch Rochlin ( topological invariants of branched superpositions of manifolds with boundaries ). He was then a professor at the State University of Leningrad (from 1974 assistant professor, from 1980 lecturer, 1986 to 1990 professor), where he completed his habilitation in 1983 (Russian doctorate, real algebraic varieties with prescribed topological properties ). Since 1986 he was also a member of the Steklov Institute in Leningrad (LOMI), where he headed the Laboratory for Geometry and Topology from 1988 to 1992. In 1992 he went to the University of California, Riverside , where he was Professor of Topology until 1997. From 1994 he was also a professor at Uppsala University , where he (like the mathematician Burglind Jöricke) was forced to resign in 2007. The resignation was based on disagreements in the faculty and caused letters of protest from, among others, the former President of the IMU Lennart Carleson and the President of the European Mathematical Society Ari Laptev. Since 2008 he has been a professor at the State University of New York at Stony Brook and is also still at the Steklow Institute in Saint Petersburg. Among other things, he was visiting professor at the University of Paris VII (2000) and at the University of California, Berkeley (2004).

In 1975 he won the Prize for Young Mathematicians of the St. Petersburg Mathematical Society .

Wiro introduced "cutting and gluing techniques" for varieties in real algebraic geometry , with which he examined their topology and, for example , was able to topologically classify the non-singular planar projective curves of degree 7 topologically (except for isotopy ). This was a contribution to the 16th Hilbert problem . Technology is one of the building blocks of tropical geometry . Together with his doctoral student Vladimir Turajew , he introduced an invariant named after both of them into topological quantum field theory .

Wiro was invited speaker at the ICM 1983 in Warsaw ( Progress in the last five years in topology of real algebraic varieties ). In 2000 he gave a plenary lecture at the European Congress of Mathematicians in Barcelona ( Dequantization of real algebraic geometry on a logarithmic paper ). In 1997 he received the Swedish Göran Gustafsson Prize. He is a fellow of the American Mathematical Society .

He is married and has two children. Besides the Russian he has the Swedish citizenship.
