Ryu Tomonaga
We prove the existence and give a classification of toric non-commutative crepant resolutions (NCCRs) of Gorenstein toric singularities whose divisor class group has rank one. More…

On silting mutations preserving global dimension
Ryu Tomonaga
A -silting object is a silting object whose derived endomorphism algebra has global dimension or less. We give an equivalent condition, which can be stated in terms of dg qu…
