Kuznetsov Categories for Gauged Linear Sigma Models
David Favero, Daniel Kaplan, Tyler L. Kelly
We define Kuznetsov and anti-Kuznetsov categories for gauged linear sigma models. We show that for complete intersections of ample divisors in smooth projective toric varieties, th…

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…

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…
