Finite order symplectic birational self-maps on Kummer-type manifolds
Yajnaseni Dutta, Dominique Mattei, Stevell Muller +1
A projective hyperkähler manifold of Kummer-type is said to be twisted modular if it is birational to the Albanese fiber of a moduli space of twisted sheaves on an abelian surface…
The Tate-Shafarevich group of a polarised K3 surface
Daniel Huybrechts, Dominique Mattei
In an earlier paper we generalised the notion of the Tate-Shafarevich group of an elliptic K3 surface to the Tate-Shafarevich group of a polarised K3 surface. In the present note,…
Obstruction classes for moduli spaces of sheaves and Lagrangian fibrations
Dominique Mattei, Reinder Meinsma
We investigate obstruction classes of moduli spaces of sheaves on K3 surfaces. We extend previous results by Caldararu, explicitly determining the obstruction class and its order i…
The special Brauer group and twisted Picard varieties
Daniel Huybrechts, Dominique Mattei
We generalise the notion of the Tate-Shafarevich group of an elliptic K3 surface with a section to the Tate-Shafarevich group of a K3 surface endowed with a linear system. The cons…
