Special Lagrangian Geometry in irreducible symplectic 4-folds
Having fixed a Kaehler class and the unique corresponding hyperkaehler metric, we prove that all special Lagrangian submanifolds of an irreducible symplectic 4-fold X are obtained by complex submanifolds via a generalization of the so called hyperkaehler rotation trick; thus they retain part of the rigidity of the complex submanifolds: indeed all special Lagrangian submanifolds of X turn out to...
متن کاملA Characterization of Certain Irreducible Symplectic 4-folds
We give a characterization of irreducible symplectic fourfolds which are given as Hilbert scheme of points on a K3 surface.
متن کاملSymplectic Geometry and Rationally Connected 4-folds
We study some symplectic geometric aspects of rationally connected 4-folds. As a corollary, we prove that any smooth projective 4-fold symplectic deformation equivalent to a Fano 4-fold of pseudo-index at least 2 or a rationally connected 4-fold whose second Betti number is 2 is rationally connected.
متن کاملDeformation theory of singular symplectic n-folds
By a symplectic manifold (or a symplectic n-fold) we mean a compact Kaehler manifold of even dimension n with a non-degenerate holomorphic 2form ω, i.e. ω is a nowhere-vanishing n-form. This notion is generalized to a variety with singularities. We call X a projective symplectic variety if X is a normal projective variety with rational Gorenstein singularities and if the regular locus U of X ad...
متن کاملRationally connected 3-folds and symplectic geometry
The first condition tells that ω is of type (1, 1). The last condition is called the taming condition. We will consider more generally taming symplectic forms α on X. These forms are thus non necessarily of type (1, 1) but their (1, 1)-part is positive (but not necessarily closed). Let X and Y be two complex projective or compact Kähler manifolds. The set of taming symplectic forms on X, resp. ...
