On the numerically and cohomologically trivial automorphisms of elliptic surfaces II:
Fabrizio Catanese, Wenfei Liu, Matthias Schütt
In this second part we study first the group of numerically trivial automorphisms of an algebraic properly elliptic surface , that is, of a minimal algebrai…

Finite symplectic automorphism groups of supersingular K3 surfaces
Hisanori Ohashi, Matthias Schütt
We give a complete classification of finite groups acting symplectically on supersingular K3 surfaces of Artin invariant one. Using work of Dolgachev and Keum, this provides the fu…
