Non-commutative crepant resolutions for some toric singularities II
Špela Špenko, Michel Van den Bergh
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…

Non-commutative crepant resolutions for some toric singularities I
Špela Špenko, Michel Van den Bergh
We give a criterion for the existence of non-commutative crepant resolutions (NCCR's) for certain toric singularities. In particular we recover Broomhead's result that a 3-dimensio…
