Fundamental group of Symp(M,w) with no circle action
Jarek Kedra
We show that the fundamental group of Symp(M,w) can be nontrivial for M that does not admit any symplectic circle action.
Characteristic classes of smooth fibrations
Tadeusz Januszkiewicz, Jarek Kedra
We construct characteristic classes of smooth (Hamiltonian) fibrations as as fiber integrals of products of Pontriagin (or Chern) classes of vertical vector bundles over the total…
Restrictions on symplectic fibrations
Jaroslaw Kedra
Moduli spaces of stable pseudoholomorphic curves can be defined parametrically, i.e. over total spaces of symplectic fibrations. This imposes several restrictions on the spectral s…
Symplectically aspherical manifolds
Raúl Ibáñez, Jarek Kȩdra, Yuli Rudyak +1
The main subjects of the paper is studying the fundamental groups of closed symplectically aspherical manifolds. Motivated by some results of Gompf, we introduce two classes of fun…
Remarks on the flux groups
Jaroslaw Kedra
I study flux groups of compact symplectic manifolds. Under some topological assumptions, I give a new estimate of the rank of flux groups and give a method of construcion of compac…
