Singularities in Calogero--Moser Varieties
Gwyn Bellamy, Ruslan Maksimau, Travis Schedler
In this article we describe completely the singularities appearing in Calogero--Moser varieties associated (at any parameter) to the wreath product symplectic reflection groups. We…
Nonprojective crepant resolutions of quiver varieties
Daniel Kaplan, Travis Schedler
In this paper, we construct a large class of examples of proper, nonprojective crepant resolutions of singularities for Nakajima quiver varieties. These include four and six dimens…
The semi-invariant ring as the Cox ring of a GIT quotient
Gwyn Bellamy, Alastair Craw, Travis Schedler
We study GIT quotients whose linearisation map defines an isomorphism between the group of characters of and the Picard group of modulo torsion. Our…
Crepant resolutions of stratified varieties via gluing
Daniel Kaplan, Travis Schedler
Let be a variety with a stratification into smooth locally closed subvarieties such that is locally a product along each stratum (e.g., a symplectic singulari…
Symplectic resolutions for multiplicative quiver varieties and character varieties for punctured surfaces
Travis Schedler, Andrea Tirelli
We study the algebraic symplectic geometry of multiplicative quiver varieties, which are moduli spaces of representations of certain quiver algebras, introduced by Crawley-Boevey a…
The Hochschild cohomology ring of a global quotient orbifold
Cris Negron, Travis Schedler, Pieter Belmans +1
We study the cup product on the Hochschild cohomology of the stack quotient [X/G] of a smooth quasi-projective variety X by a finite group G. More specifically, we construct a G-eq…
