Title: Categorical crepant resolutions and schobers
Date (JST): Fri, Dec 05, 2025, 13:30 - 15:00
Place: Seminar Room B
Abstract:
Categorical crepant resolutions in the sense of Kuznetsov are modeled on the adjunction of derived categories associated to a crepant resolution of a rational singularity. I will discuss compatibilities between these and schobers, in particular spherical functors and spherical pairs, with applications to general flopping contractions of 3-folds.
