Algebra Seminar

Tits cone intersections and Applications

Michael Wemyss (Glasgow)

Location:  https://rutgers.zoom.us/j/95075528338
Date & time: Wednesday, 04 November 2020 at 2:00PM - 3:00PM

In the first half of the talk, I will give an overview of Tits cone intersections, which are structures that can be obtained from (possibly affine) ADE Dynkin diagrams, together with a choice of nodes. This is quite elementary, but visually very beautiful, and it has some really remarkable features and applications. 
In the second half of the talk I will highlight some of the applications to algebraic geometry, mainly to 3-fold flopping contractions, through mutation and stability conditions. This should be viewed as a categorification of the first half of my talk. Parts are joint work with Yuki Hirano, parts with Osamu Iyama.
