*Dennis Gaitsgory is a professor of mathematics at Harvard University known for his research on the geometric Langlands program. His work in geometric Langlands culminated in a joint 2002 paper with Edward Frenkel and Kari Vilonen, On the geometric Langlands conjecture establishing the conjecture for finite fields, and a separate 2004 paper, On a vanishing conjecture appearing in the geometric Langlands correspondence, generalizing the proof to include the field of complex numbers as well.*

**21 мая – 9 июня 2017г.** / **Andrei Negut** / MIT, Dep. of Mathematics / [ Website ] /

Assistant Professor of Mathematics / Algebraic Geometry, Representation Theory

Andrei Negut’s overall program concentrates on problems in geometric representation theory, an area that overlaps studies in algebraic geometry and representation theory. His results connect to areas in mathematical physics, symplectic geometry, combinatorics and probability theory. His current research focuses on moduli of sheaves, quiver varieties, quantum algebras and knot invariants.

Negut received the PhD from Columbia University in 2015, studying under Andrei Okounkov. He completed the Master’s in mathematics from Harvard in 2012, and the B.A. from Princeton in 2009
