Bimeromorphic automorphism groups of non-projective hyperkähler manifolds - a note inspired by C. T. McMullen
Keiji Oguiso
Being inspired by a work of Curtis T. McMullen about a very impressive automorphism of a K3 surface of Picard number zero, we shall clarify the structure of the bimeromorphic autom…
The Alternating Group of degree 6 in Geometry of the Leech Lattice and K3 Surfaces
JongHae Keum, Keiji Oguiso, De-Qi Zhang
The alternating group of degree 6 is located at the junction of three series of simple non-commutative groups : simple sporadic groups, alternating groups and simple groups of Lie…
A characterization of the Fermat quartic K3 surface by means of finite symmetries
Keiji Oguiso
We shall characterize the Fermat K3 surface, among all complex K3 surfaces, by means of its finite group symmetries.
Counting Unimodular Lattices in
Shinobu Hosono, Bong H. Lian, Keiji Oguiso +1
Narain lattices are unimodular lattices {\it in} , subject to certain natural equivalence relation and rationality condition. The problem of describing and counting these…
