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…
The 3-divisibility of divisors on K3 surfaces in characteristic 3
Toshiyuki Katsura, Matthias Schütt
We describe the possible 3-divisible configurations of smooth rational curves on K3 surfaces in characteristic 3 and fully classify the resulting triple covers.
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…
On the moduli space of stable surfaces with realizing the minimal volume
Valery Alexeev, Wenfei Liu, Matthias Schütt
Let be the moduli space of the KSBA stable surfaces of geometric genus realizing the minimal possible volume . We show that its reduced part…
On the cohomologically trivial automorphisms of elliptic surfaces I:
Fabrizio Catanese, Davide Frapporti, Christian Gleissner +2
In this first part we describe the group of cohomologically trivial automorphisms of a properly elliptic surface (a minimal surface with Kodaira dimension…
