A Classification of Star Log Symplectic Structures on a Compact Oriented Surface
نویسنده
چکیده
Given a compact oriented surface, we classify log Poisson bivectors whose degeneracy loci are locally modeled by a finite set of lines in the plane intersecting at a point. Further, we compute the Poisson cohomology of such structures and discuss the relationship between our classification and the second Poisson cohomology.

On Compact Symplectic Manifolds with Lie Group Symmetries
In this note we give a structure theorem for a finite-dimensional subgroup of the automorphism group of a compact symplectic manifold. An application of this result is a simpler and more transparent proof of the classification of compact homogeneous spaces with invariant symplectic structures. We also give another proof of the classification from the general theory of compact homogeneous spaces...
متن کاملAn 8-dimensional Non-formal Simply Connected Manifold
Using Gompf construction [5], we show an 8–dimensional simply connected and compact oriented manifold which is non-formal. Moreover we prove that such a manifold admits a symplectic structure. In this short note, we construct an example of a compact simply connected and symplectic 8–dimensional manifold which is non-formal. Such a manifold M is obtained as the Gompf connected sum [5] of the man...

An introduction to the moduli space of holomorphic fiber bundles M n (Σ) on a compact Riemann surface Σ is presented and a formula for the regularised determinant and an other for the symplectic form at trivial bundle is proposed. Classification AMS 53C07.
متن کاملA Six Dimensional Compact Symplectic Solvmanifold without Kahler Structures
Gordon and Benson have proved that if a compact nilmanifold admits a Kahler structure then it is a torus [5] more precisely they proved that the condition (iv) fails for any symplectic structure on a non-toral nilmanifold M. This result was independently proved by Hasegawa [12] by showing that (v) fails for M. For a compact solvmanifold M of dimension 4 it is known that M has a Kahler structure...
متن کاملA compact symmetric symplectic non-Kaehler manifold dg-ga/9601012
In this paper I construct, using off the shelf components, a compact symplectic manifold with a non-trivial Hamiltonian circle action that admits no Kaehler structure. The non-triviality of the action is guaranteed by the existence of an isolated fixed point. The motivation for this work comes from the program of classification of Hamiltonian group actions. The Audin-Ahara-Hattori-Karshon class...
