Noncommutative deformation theory, the derived quotient, and DG singularity categories

28 Nov 2018 Booth Matt

We show that Braun-Chuang-Lazarev's derived quotient prorepresents a naturally defined noncommutative derived deformation functor. Given a noncommutative partial resolution of a Gorenstein algebra, we show that the associated derived quotient controls part of its dg singularity category... (read more)
