Multiple fibers of holomorphic Lagrangian fibrations
Jun-Muk Hwang, Keiji Oguiso
We determine all possible multiplicities of general singular fibers of a holomorphic Lagrangian fibration, under the assumption that all components of the fibers are of Fujiki clas…
Automorphisms of rational manifolds of positive entropy with Siegel disks
Keiji Oguiso, Fabio Perroni
Using McMullen's rational surface automorphisms, we construct projective rational manifolds of higher dimension admitting automorphisms of positive entropy with arbitrarily high nu…
The third smallest Salem number in automorphisms of K3 surfaces
Keiji Oguiso
We realize the logarithm of the third smallest known Salem number as the topological entropy of a K3 surface automorphism with a Siegel disk and a pointwisely fixed curve at the sa…
A remark on dynamical degrees of automorphisms of hyperkähler manifolds
Keiji Oguiso
We describe all the dynamical degrees of automorphisms of hyperkähler manifolds in terms of the first dynamical degree. We also present two explicit examples of different geometric…
Picard number of the generic fiber of an abelian fibered hyperkaehler manifold
Keiji Oguiso
We shall show that the Picard number of the generic fiber, in the sense of scheme, of an abelian fibered hyperkähler manifold over the projective space is always one. We then give…
