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.
On nondegenerate coupling forms
J. Kedra, A. Tralle, A. Woike
The aim of the present paper is to investigate new classes of symplectically fat fibre bundles. We prove a general existence theorem for fat vectors with respect to the canonical i…
Non-symplectic smooth circle actions on symplectic manifolds
Boguslaw Hajduk, Krzysztof Pawalowski, Aleksy Tralle
We present some methods to construct smooth circle actions on symplectic manifolds with non-symplectic fixed point sets or non-symplectic cyclic isotropy point sets. All such actio…
Symplectic forms invariant under free circle actions on 4--manifolds
Boguslaw Hajduk, Rafal Walczak
Let be a smooth compact manifold with a free circle action generated by a vector field Then for any invariant symplectic form on the contracted form is n…
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…
On certain geometric and homotopy properties of closed symplectic manifolds
Raúl Ibáñez, Yuli Rudyak, Aleksy Tralle +1
The paper deals with relations between the Hard Lefschetz property, (non)vanishing of Massey products and the evenness of odd-degree Betti numbers of closed symplectic manifolds. I…
On Symplectically Harmonic Forms on Six-dimensional Nilmanifolds
R. Ibáñez, Yu. Rudyak, A. Tralle +1
In the present paper we study the variation of the dimensions of spaces of symplectically harmonic cohomology classes (in the sense of Brylinski) on closed symplectic manifol…
