Informal Representation Theory and Mathematical Physics Seminar

Informal Representation Theory and Mathematical Physics Seminar (the former PD seminar) is organized by myself, where I asks people in Kyoto (and visitors sometime) to give expository talks. The topics and speakers are chosen by myself, and audiences are supposed to give a talk once par a semester unless I approve.

2013 Summer Schedule

In this semester, the style is different from the ordinary one. We first learn basic on W-algebras following Frenkel-BenZvi [F-BZ], and then study the paper by Maulik-Okounkov [MO]. Finally Nakajima will explain the joint work in progress with Braverman and Finkelberg.

Apr. 18, W-algebra [F-BZ] 1, Ryosuke Kodera
Apr. 25, W-algebras [F-BZ] 2, Ryosuke Kodera
May 2, W-algebras [F-BZ] 3, Ryosuke Kodera + Opers 1, Hiraku Nakajima
May 9, Opers 2, Hiraku Nakajima
I explain 0-opers and Hitchin hamiltonian following [BD].
May 16, BRST cohomology, Yuuya Takayama
May 23, [MO] 1, Hiraku Nakajima
May 30, [MO] 2, Hiraku Nakajima
June 6, no seminar
June 13, no seminar
