Extensions of the alternating group of degree 6 in the geometry of K3 surfaces

JongHae Keum, Keiji Oguiso, De-Qi Zhang

We shall determine the uniquely existing extension of the alternating group of degree 6 (being normal in the group) by a cyclic group of order 4, which can act on a complex K3 surf…

Automorphisms of hyperkähler manifolds in the view of topological entropy

Keiji Oguiso

First we show that any group of automorphisms of null-entropy of a projective hyperkähler manifold is almost abelian of rank at most . We then characterize automorphi…
