No cohomologically trivial non-trivial automorphism of generalized Kummer manifolds
Keiji Oguiso
We prove that the natural representaion, on the total Betti cohomolgy group, of the automorphism group of a hyperkähler manifold deformation equivalent to a generalized Kummer mani…
Smooth quartic K3 surfaces and Cremona transformations, II
Keiji Oguiso
This is a continuation of [Og12], concerning automorphisms of smooth quartic K3 surfaces and birational automorphisms of ambient projective three spaces.
Automorphism groups of Calabi-Yau manifolds of Picard number two
Keiji Oguiso
We prove that the automorphism group of an odd dimensional Calabi-Yau manifold of Picard number two is always a finite group. This makes a sharp contrast to the automorphism groups…
Free automorphisms of positive entropy on smooth Kähler surfaces
Keiji Oguiso
We prove that there is a projective K3 surface admitting a (fixed point) free automorphism of positive entropy and that no smooth compact Kähler surface other than projective K3 su…
