Dennis Gaitsgory

Dennis Gaitsgory (* Moldova) is an Israeli- American mathematician who deals with geometric representation theory (for example, the so-called geometric Langlands program).

Gaitsgory was born in present-day Moldova and grew up in Tajikistan. He studied from 1990 at the University of Tel Aviv, where he received his doctorate in 1997 with Joseph Bernstein ( Automorphic Sheaves and Eisenstein Series). 1996/1997 and 1998/99 he was at the Institute for Advanced Study. In 2001 he was an associate professor at the University of Chicago and from 2005 professor at Harvard University, where he was a Junior Fellow in 1997.

He is known for his work in the geometric Langlands program. With Edward Frenkel and Kari Vilonen he proved in 2000 the geometric Langlands conjecture for curves over finite fields, expanded in 2002 to the case of curves over the complex numbers ( field of characteristic 0)

2002 to 2004 he was Clay Research Fellow. In 2000 he won the EMS price. In 2002 he was invited speaker at the International Congress of Mathematicians in Beijing (Geometric Langlands correspondence for).
