Deformations of log symplectic structures on surfaces

Melinda Lanius (UIUC)

Abstract: A star log symplectic bi-vector on a surface has a degeneracy loci locally modelled by a finite set of lines in the plane intersecting at a point. We will discuss two ways to capture the behaviour of their deformations: one `global' and one more `local' in flavor. From a global perspective, we classify all star log symplectic structures on compact surfaces up to symplectomorphism by some associated Lie algebroid de Rham cohomology classes. In a more local snap shot, we compute the Poisson cohomology of these structures and discuss the relationship of our classification and the second Poisson cohomology.
