Log Centres of Noncommutative Crepant Resolutions are Kawamata Log Terminal: Remarks on a paper of Stafford and van den Bergh
Abstract
We show that if a finitely generated prime algebra is a finitely generated maximal Cohen-Macaulay module over its centre Z, and has global dimension equal to Z, then the pair given by its centre and ramification divisor is Kawamata log terminal.
