Spherical Twists for Gorenstein Orders and -Hilb
Marina Godinho
This paper constructs derived autoequivalences of Gorenstein orders as twists around spherical functors. More precisely, given a Gorenstein order and a quotient $p \colon A \to…

A twist on ring morphisms and crepant contractions
Marina Godinho
Given a ring morphism, this paper constructs the twist functor around the induced derived restriction of scalars functor. We prove that the twist around ring morphisms is a derived…
