Time | Venue | Title/Abstract |
---|---|---|

Mar 21, 2017, 18:30-20:00 | Room-1106 | Introduction 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. | ||
