Criteria for the existence of equivariant fibrations on algebraic surfaces and hyperkähler manifolds and equality of automorphisms up to powers - a dynamical viewpoint
Fei Hu, JongHae Keum, De-Qi Zhang
Let be a projective surface or a hyperkähler manifold and . We give a necessary and sufficient condition for the existence of a non-trivial -equivariant fibrat…

K3 surfaces with an order 50 automorphism
JongHae Keum
In any characteristic different from 2 and 5, Kondō gave an example of a K3 surface with a purely non-symplectic automorphism of order 50. The surface was explicitly given as a dou…
