A McKay correspondence for reflection groups
Ragnar-Olaf Buchweitz, Eleonore Faber, Colin Ingalls
We construct a noncommutative desingularization of the discriminant of a finite reflection group as a quotient of the skew group ring . If is generated by order two…
The minimal model program for b-log canonical divisors and applications
Daniel Chan, Kenneth Chan, Louis de Thanhoffer de Völcsey +8
We discuss the minimal model program for b-log varieties, which is a pair of a variety and a b-divisor, as a natural generalization of the minimal model program for ordinary log va…
Period-index bounds for arithmetic threefolds
Benjamin Antieau, Asher Auel, Colin Ingalls +2
The standard period-index conjecture for the Brauer group of a field of transcendence degree 2 over a -adic field predicts that the index divides the cube of the period. Using G…
Homological behavior of idempotent subalgebras and Ext algebras
Colin Ingalls, Charles Paquette
Let be a (left and right) Noetherian ring that is semiperfect. Let be an idempotent of and consider the ring and the semi-simple right -module $S_e…
Noncommutative resolutions of discriminants
Ragnar-Olaf Buchweitz, Eleonore Faber, Colin Ingalls
We give an introduction to the McKay correspondence and its connection to quotients of by finite reflection groups. This yields a natural construction of noncommutat…
