Crepant Resolutions of Gorenstein Toric Singularities and Upper Bound Theorem
Abstract
Description
A necessary condition for the existence of torus-equivariant crepant resolutions of Gorenstein toric singularities can be derived by making use of a variant of the classical Upper Bound Theorem which is valid for simplicial balls.
