On the number of components of the symplectic representatives of the canonical class

Journal of the European Mathematical Society
Similarity:
We show that there exists a family of simply connected, symplectic 4-manifolds such that the (Poincaré dual of the) canonical class admits both connected and disconnected symplectic representatives. This answers a question raised by Fintushel and Stern.

Reductions of locally conformal symplectic structures and de Rham cohomology tangent to a foliation
Wojciech Domitrz (2008)
Banach Center Publications
Similarity:
We define a procedure of reduction of locally conformal symplectic structures. We find a necessary and sufficient condition for this reduction to hold in terms of a special kind of de Rham cohomology class (tangent to the characteristic foliation) of the Lee form.
