A two-cocycle on the group of symplectic diffeomorphisms
Światosław R. Gal, Jarek Kędra
We investigate a two-cocycle on the group of symplectic diffeomorphisms of an exact symplectic manifolds defined by Ismagilov, Losik, and Michor and investigate its properties. We…
On the algebraic independence of Hamiltonian characteristic classes
Swiatoslaw Gal, Jarek Kedra, Aleksy Tralle
We prove that Hamiltonian characteristic classes defined as fibre integrals of powers of the coupling class are algebraically independent for generic coadjoint orbits.
A cocycle on the group of symplectic diffeomorphisms
Swiatoslaw R. Gal, Jarek Kedra
We define a cocycle on the group of symplectic diffeomorphisms of a symplectic manifold and investigate its properties. The main applications are concerned with symplectic actions…
Symplectic configurations
Swiat Gal, Jarek Kedra
We define a class of symplectic fibrations called symplectic configurations. They are natural generalization of Hamiltonian fibrations. Their geometric and topological properties a…
