Deformations of log-symplectic structures
We describe the space of Poisson bivectors near a log-symplectic structure up to small diffeomorphisms.

On cohomological obstructions to the existence of log symplectic structures
We prove that a compact log symplectic manifold has a class in the second cohomology group whose powers, except maybe for the top, are nontrivial. This result gives cohomological obstructions for the existence of b-log symplectic structures similar to those in symplectic geometry.
