Algebraic Geometry Seminar: Crepant resolutions via stacks
Jeremy Usatine, Florida State University
Consider an invariant that behaves nicely for smooth varieties, such as Euler number, Betti numbers, or Hodge numbers. Suppose we want a...
Algebraic Geometry Seminar: Proof of Miyanishi's conjecture on endomorphisms of varieties
Supravat Sarkar (Princeton University)
If X is a quasi-projective variety over a field k and f is a birational endomorphism of X that is injective outside a closed subset of...
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...
