Non-commutative crepant resolutions for some toric singularities II

Published 25 Jul 2017 in math.AG and math.RA | (1707.08245v3)

Abstract: Using the theory of dimer models Broomhead proved that every 3-dimensional Gorenstein affine toric variety Spec R admits a toric non-commutative crepant resolution (NCCR). We give an alternative proof of this result by constructing a tilting bundle on a (stacky) crepant resolution of Spec R using standard toric methods. Our proof does not use dimer models.
