In May 2012, the Geometric Structures Laboratory (a Fields Institute General Scientific Activity) convened for a "Geometry Retreat", commencing a period of concentrated study on the subjects of moduli spaces, wall-crossing, and integrable systems. This Master Class is a component of that period of study.

While the Master Class is designed especially for graduate students and young researchers who wish to have greater exposure to these geometric themes, senior researchers will also be interested in the content of the lectures. The Master Class is open to all who wish to attend. (In particular, you will not have had to have attended any Geometric Structures Lab sessions.)

Daniel Halpern-Leistner's lectures will concern wall-crossing in GIT, the derived geometry of GIT quotients, "generalized flops", derived Kirwan surjectivity, and other related ideas emerging in his work.

Schedule


7 pm on Monday, March 25
6:30 pm on Tuesday, March 26
6:30 pm on Wednesday, March 27
6:30 pm on Thursday, March 28

All lectures will be held in Bahen Centre 6183.

The lectures will be roughly 1.5 - 2 hours long, not including questions and discussion.
We plan for significant discussion during and after the lectures.

Prep Course


There will be an examples-driven prep course for graduate students, the week prior to the Master Class.

Jonathan Fisher will give lectures on GIT.
Brent Pym will give a lecture on derived categories.

12 pm - 2 pm on Tuesday, March 19 in BA026: Jonathan
2:30 pm - 4 pm on Wednesday, March 20 in AP124: Jonathan
5:30 pm - 7:30 pm on Wednesday, March 20 in BA6180: Jonathan
