Symplectic 4-manifolds with fixed point free circle actions
Symplectic 4-manifolds point free circle actions Geometric Topology
2012/6/19
We show that recent results of Friedl-Vidussi and Chen imply that a symplectic manifold admits a fixed point free circle action if and only if it admits a symplectic circle action and we give a comple...
On homotopy Poisson actions and reduction of symplectic Q-manifolds
homotopy Poisson actions reduction of symplectic Q-manifolds

We present a general framework for reduction of symplectic Qmanifolds via graded group actions. In this framework, the homological structure on the acting group is a multiplicative multivector field.

Simply connected symplectic 4-manifolds with positive signature。
This paper has two essentially unrelated halves. In the first we prove that a closed symplectic four-manifold admitting a fibration by connected, homologically essential Lagrangian tori with "tame" si...
Braids and symplectic four-manifolds with abelian fundamental group
four-manifolds abelian fundamental group
2010/3/1
We explain how a version of Floer homology can be used as an invariant of symplectic manifolds with b1>0. As a concrete example, we look at four-manifolds produced from braids by a surgery constructio...
