Time: Tuesday noon 12:00-13:30. (the time slot is updated) 
Venue: School of Mathematics SJTU, Room-1106.

Room-1106Introduction to Springer theory
This is the first talk of my proposed seminar on Weyl group, Springer theory, Hecke algebra and related topics. As an orientation, I will first explain the content of Springer correspondence. Then I will briefly review the basic idea of the constructions of the Springer correspondence. In the end, I will discuss some relationships of the Springer theory with other fields, such as combinatorics and representation theory of reductive groups. If time permits, I will also discuss the generalized Springer correspondence.

Room-1106A proof of Springer correspondence by Chriss-Ginzburg, (I)
I will present a proof of the Springer correspondence following Chriss-Ginzburg's book "Representation Theory and Complex Geometry" in the next two or three talks. In this talk, I plan to discuss the geometry of the flag variety and the Steinberg variety.
