Symplectic Manifolds: Gromov-Witten Invariants on Symplectic and Almost Contact Metric Manifolds [PDF]
In this chapter, we introduce Gromov-Witten invariant, quantum cohomology, Gromov-Witten potential, and Floer cohomology on symplectic manifolds, and in connection with these, we describe Gromov-Witten type invariant, quantum type cohomology, Gromov ...

Almost contact metric submersions and symplectic manifolds
In this paper, we discuss some geometric properties of almost contact metric submersions involving symplectic manifolds. We show that this is obtained if the total space is an b-almost Kenmotsu manifold.

Symplectic Groupoids and Generalized Almost Contact Manifolds [PDF]
We obtain equivalent assertions among the integrability conditions of generalized almost contact manifolds, the condition of compatibility of source and target maps of symplectic groupoids with symplectic form and generalized contact ...

The topology of Stein fillable manifolds in high dimensions II [PDF]
We continue our study of contact structures on manifolds of dimension at least five using complex surgery theory. We show that in each dimension 2q+1 > 3 there are 'maximal' almost contact manifolds to which there is a Stein cobordism from any other (2q ...

Contact pairs and locally conformally symplectic structures [PDF]
We discuss a correspondence between certain contact pairs on the one hand, and certain locally conformally symplectic forms on the other. In particular, we characterize these structures through suspensions of contactomorphisms.

On the geometry of almost $\mathcal{S}$-manifolds [PDF]
An $f$-structure on a manifold $M$ is an endomorphism field $\phi$ satisfying $\phi^3+\phi=0$. We call an $f$-structure {\em regular} if the distribution $T=\ker\phi$ is involutive and regular, in the sense of Palais.

Inequivalent contact structures on Boothby-Wang 5-manifolds
We consider contact structures on simply-connected 5-manifolds which arise as circle bundles over simply-connected symplectic 4-manifolds and show that invariants from contact homology are related to the divisibility of the canonical class of the ...

Generalized Contact Structures
We study integrability of generalized almost contact structures, and find conditions under which the main associated maximal isotropic vector bundles form Lie bialgebroids. These conditions differentiate the concept of generalized contact structures from

Locally conformal symplectic nilmanifolds with no locally conformal K\"ahler metrics [PDF]
We obtain an example of a compact locally conformal symplectic nilmanifold which admits no locally conformal K\"ahler metrics. This gives a new positive answer to a question raised by L. Ornea and M. Verbitsky.Comment: 7 pages, no figures.

Given a group $G$ and a class of manifolds $\CC$ (e.g. symplectic, contact, K\"ahler etc), it is an old problem to find a manifold $M_G \in \CC$ whose fundamental group is $G$. This article refines it: for a group $G$ and a positive integer $r$ find $M_G
