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...
Topological centers of $n-$th dual of module actions
Arens regularity bilinear mappings Topological center n-th dual
2011/2/21
In this paper, we will study the topological centers of n−th dual of Banach A−module and we extend some propositions from Lau and ¨Ulger into n−th dual of Banach A−modules wher...

This is a note of my lectures at “Advanced courses in Foliation” in the research program “Foliation”, which was held at the Centre de Recerca Mathem`atica in the May of 2010. In this note, we discuss ...
The equivariant cohomology of isotropy actions on symmetric spaces
equivariant cohomology of isotropy actions symmetric spaces
2010/12/9
We show that for every symmetric space G=K of compact type with K connected, the K-action on G=K by left translations is equivariantly formal.
Torsion in equivariant cohomology and Cohen-Macaulay G-actions
Torsion equivariant cohomology Cohen-Macaulay G-actions
2010/11/26
We show that the well-known fact that the equivariant cohomology of a torus action is a torsion-free module if and only if the map induced by the inclusion of the xed point set is injective generalis...
