Crepant Resolutions of Stratified Varieties via Gluing
Crepant Resolutions of Stratified Varieties via Gluing
Abstract Let $X$ be a variety with a stratification ${\mathcal{S}}$ into smooth locally closed subvarieties such that $X$ is locally a product along each stratum (e.g., a symplectic singularity). We prove that assigning to each open subset $U \subset X$ the set of isomorphism classes of locally projective crepant resolutions …
