چکیده

Assume (M,ω) is a connected, compact 6 dimensional symplectic manifold equipped with a semi-free Hamiltonian circle action, such that the fixed point set consists of isolated points or compact orientable surfaces. We restrict attention to the case dim H(M) < 3. We give a complete list of the possible manifolds, determine their equivariant cohomology ring and equivariant Chern classes. Some of these manifolds are classified up to diffeomorphism. We also show the existence for a few cases.

On the Construction of Certain 6-dimensional Symplectic Manifolds with Hamiltonian Circle Actions

Let (M, ω) be a connected, compact 6-dimensional symplectic manifold equipped with a semi-free Hamiltonian S action such that the fixed point set consists of isolated points or surfaces. Assume dim H(M) < 3, in [L], we defined a certain invariant of such spaces which consists of fixed point data and twist type, and we divided the possible values of these invariants into six “types”. In this pap...

A 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...

Symplectic actions of 2-tori on 4-manifolds

We classify symplectic actions of 2-tori on compact, connected symplectic 4-manifolds, up to equivariant symplectomorphisms, hence extending the theory of Atiyah, Guillemin–Sternberg, Delzant and Benoist to actions of tori which are not necessarily Hamiltonian. The classification is in terms of a collection of up to nine invariants. We construct an explicit model of such symplectic manifolds wi...

The Log-concavity Conjecture for the Duistermaat-heckman Measure Revisited

Karshon constructed the first counterexample to the log-concavity conjecture for the Duistermaat-Heckman measure: a Hamiltonian six manifold whose fixed points set is the disjoint union of two copies of T. In this article, for any closed symplectic four manifold N with b > 1, we show that there is a Hamiltonian circle manifold M fibred over N such that its DuistermaatHeckman function is not log...

Quantum Cohomology and S-actions with Isolated Fixed Points

This paper studies symplectic manifolds that admit semi-free circle actions with isolated fixed points. We prove, using results on the Seidel element [4], that the (small) quantum cohomology of a 2n dimensional manifold of this type is isomorphic to the (small) quantum cohomology of a product of n copies of P. This generalizes a result due to Tolman and Witsman [11].
