Symplectic Cutting of Kähler Manifolds

چکیده

We obtain estimates on the character of the cohomology of an S-equivariant holomorphic vector bundle over a Kähler manifold M in terms of the cohomology of the Lerman symplectic cuts and the symplectic reduction of M . In particular, we prove and extend inequalities conjectured by Wu and Zhang [12]. The proof is based on constructing a flat family of complex spaces Mt (t ∈ C) such that Mt is isomorphic to M for t 6= 0, while M0 is a singular reducible complex space, whose irreducible components are the Lerman symplectic cuts.

A Note on Higher Cohomology Groups of Kähler Quotients

Consider a holomorphic torus action on a possibly non-compact Kähler manifold. We show that the higher cohomology groups appearing in the geometric quantization of the symplectic quotient are isomorphic to the invariant parts of the corresponding cohomology groups of the original manifold. For non-Abelian group actions on compact Kähler manifolds, this result was proved recently by Teleman and ...

Cohomologically Kähler Manifolds with No Kähler Metrics

We show some examples of compact symplectic solvmanifolds, of dimension greater than four, which are cohomologically Kähler and do not admit Kähler metric since their fundamental groups cannot be the fundamental group of any compact Kähler manifold. Some of the examples that we study were considered by Benson and Gordon (1990). However, whether such manifolds have Kähler metrics was an open que...

Non-Kähler symplectic manifolds with toric symmetries

Drawing on the classification of symplectic manifolds with cosiotropic principal orbits by Duistermaat and Pelayo, in this note we exhibit families of compact symplectic manifolds, such that (i) no two manifolds in a family are homotopically equivalent, (ii) each manifold in each family possesses Hamiltonian, and non-Hamiltonian, toric symmetries, (iii) each manifold has odd first Betti number ...

Cohomology algebras in symplectic, Kähler and algebraic geometry

We show a number of applications to geometry of the study of cohomology algebras of various kinds of manifolds. The main tool is Hodge theory, and we use it to show that projective complex manifolds are more restricted topologically than compact Kähler manifolds. We also make explicit numerous constraints satisfied by cohomology algebras of compact Kähler manifolds, making them very non generic...

On Monodromies of a Degeneration of Irreducible Symplectic Kähler Manifolds

We study the monodromy operators on the Betti cohomologies associated to a good degeneration of irreducible symplectic manifold and we show that the unipotency of the monodromy operator on the middle cohomology is at least the half of the dimension. This implies that the “mildest” singular fiber of a good degeneration with non-trivial monodromy of irreducible symplectic manifolds is quite diffe...
