Periods of Enriques Manifolds
Keiji Oguiso, Stefan Schroeer
Enriques manifolds are complex spaces whose universal coverings are hyperkaehler manifolds. We introduce period domains for Enriques manifolds, establish a local Torelli theorem, a…
Local structure of principally polarized stable Lagrangian fibrations
Jun-Muk Hwang, Keiji Oguiso
A holomorphic Lagrangian fibration is stable if the characteristic cycles of the singular fibers are of type or . We will give a complete descr…
Bounded derived categories of very simple manifolds
Keiji Oguiso
An unrepresentable cohomological functor of finite type of the bounded derived category of coherent sheaves of a compact complex manifold of dimension greater than one with no prop…
A simple remark on a flat projective morphism with a Calabi-Yau fiber
Keiji Oguiso
If a K3 surface is a fiber of a flat projective morphisms over a connected noetherian scheme over the complex number field, then any smooth connected fiber is also a K3 surface. Ob…
Enriques manifolds
Keiji Oguiso, Stefan Schroeer
Using the theory of hyperkahler manifolds, we generalize the notion of Enriques surfaces to higher dimensions and construct several examples using group actions on Hilbert schemes…
