Subvarieties in non-compact hyperkähler manifolds

چکیده
Let M be a hyperkähler manifold, not necessarily compact, and S ∼= CP 1 the set of complex structures induced by the quaternionic action. Trianalytic subvariety of M is a subvariety which is complex analytic with respect to all I ∈ CP . We show that for all I ∈ S outside of a countable set, all compact complex subvarieties Z ⊂ (M, I) are trianalytic. For M compact, this result was proven in [V1] using Hodge theory.

Parabolic nef currents on hyperkähler manifolds
LetM be a compact, holomorphically symplectic Kähler manifold, and η a (1,1)-current which is nef (a limit of Kähler forms). Assume that the cohomology class of η is parabolic, that is, its top power vanishes. We prove that all Lelong sets of η are coisotropic. When M is generic, this is used to show that all Lelong numbers of η vanish. We prove that any hyperkähler manifold with Pic(M) = Z has...
متن کاملLagrangian Submanifolds in Hyperkähler Manifolds, Legendre Transformation
We develop the foundation of the complex symplectic geometry of Lagrangian subvarieties in a hyperkähler manifold. We establish a characterization, a Chern number inequality, topological and geometrical properties of Lagrangian submanifolds. We discuss a category of Lagrangian subvarieties and its relationship with the theory of Lagrangian intersection. We also introduce and study extensively a...
متن کاملA Problem List for Compact Hyperkähler Manifolds
In his thesis, Caldararu described twisted Fourier-Mukai transforms for elliptic fibrations. In this talk I will describe how certain holomorphic symplectic manifolds can be deformed to integrable systems, i.e. fibrations by abelian varieties. These are higher dimensional analogues of elliptic K3 surfaces, and twisted Fourier-Mukai transforms
متن کاملVanishing theorems for locally conformal hyperkähler manifolds
Let M be a compact locally conformal hyperkähler manifold. We prove a version of Kodaira-Nakano vanishing theorem for M . This is used to show that M admits no holomorphic differential forms, and the cohomology of the structure sheaf H(OM ) vanishes for i > 1. We also prove that the first Betti number of M is 1. This leads to a structure theorem for locally conformally hyperkähler manifolds, de...
متن کاملWarped product and quasi-Einstein metrics
Warped products provide a rich class of physically significant geometric objects. Warped product construction is an important method to produce a new metric with a base manifold and a fibre. We construct compact base manifolds with a positive scalar curvature which do not admit any non-trivial quasi-Einstein warped product, and non compact complete base manifolds which do not admit any non-triv...
