Fundamental groups of open K3 surfaces, Enriques surfaces and Fano 3-folds
J. Keum, D. -Q. Zhang
We investigate when the fundamental group of the smooth part of a K3 surface or Enriques surface with Du Val singularities, is finite. As a corollary we give an effective upper bou…

Some remarks on the universal cover of an open K3 surface
Fabrizio Catanese, JongHae Keum, Keiji Oguiso
We shall give, in an optimal form, a sufficient numerical condition for the finiteness of the fundamental group of the smooth locus of a normal K3 surface. We shall moreover prove…

Birational automorphisms of quartic Hessian surfaces
Igor V. Dolgachev, Jonghae Keum
We find generators of the group of birational automorphisms of the Hessian surface of a general cubic surface. Its nonsingular minimal model is a K3 surface with the Picard lattice…
