Homological projective duality for the Segre cubic
Thorsten Beckmann, Pieter Belmans
The Segre cubic and Castelnuovo-Richmond quartic are two projectively dual hypersurfaces in , with a long and rich history starting in the 19th century. We will expla…
Equivariant categories of symplectic surfaces and fixed loci of Bridgeland moduli spaces
Thorsten Beckmann, Georg Oberdieck
Given an action of a finite group on the derived category of a smooth projective variety we relate the fixed loci of the induced -action on moduli spaces of stable objec…
On equivariant derived categories
Thorsten Beckmann, Georg Oberdieck
We study the equivariant category associated to a finite group action on the derived category of coherent sheaves of a smooth projective variety. We discuss decompositions of the e…
Birational geometry of moduli spaces of stable objects on Enriques surfaces
Thorsten Beckmann
Using wall-crossing for K3 surfaces, we establish birational equivalence of moduli spaces of stable objects on generic Enriques surfaces for different stability conditions. As an a…
