Title: | Non-Commutative Crepant Resolutions for Some Toric Singularities I | Authors: | SPENKO, Spela VAN DEN BERGH, Michel |
Issue Date: | 2020 | Publisher: | OXFORD UNIV PRESS | Source: | INTERNATIONAL MATHEMATICS RESEARCH NOTICES, 2020 (21) , p. 8120 -8138 | Abstract: | We give a criterion for the existence of noncommutative crepant resolutions (NCCRs) for certain toric singularities. In particular, we recover Broomhead's result that a three-dimensional toric Gorenstein singularity has an NCCR. Our result also yields the existence of an NCCR for a four-dimensional toric Gorenstein singularity, which is known to have no toric NCCR. | Notes: | Van den Bergh, M (corresponding author), Univ Edinburgh, Sch Math, James Clerk Maxwell Bldg,Kings Bldg, Edinburgh EH9 3FD, Midlothian, Scotland. michel.vandenbergh@uhasselt.be |
