On Locally Homogeneous Aspherical Kahler Manifolds
Yoshinobu Kamishima (Josai University)
Abstract:
We shall prove that a compact locally homogeneous aspherical Kӓhler manifold
is holomorphically isometric to a quotient of the product
by a discrete subgroup
which becomes a holomorphic toral bundle over a Hermitian symmetric orbifold
. The isometry classification on
reduces to that of holomorphic isometric actions of
on
, while
admits a group extension of a Bieberbach group by the product of a Mostow rigidity group and a surface group. The Seifert rigidity applies to show
is always smoothly rigid.
