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…
