Algebraic Geometry Seminar: From stability conditions to generalized Bogomolov-Gieseker inequalities
Xiaolei Zhao (UC Santa Barbara)
The classical Bogomolov-Gieseker inequality provides a bound on the second Chern character of semistable sheaves, which is an essential...
Algebraic Geometry Seminar: Stable map resolutions of Richardson varieties
Allen Knutson (Cornell)
Given a circle action S on a projective variety X, we introduce the "stable map quotient" using Kontsevich's space of stable...
