Title: Shadows of Symplectic Geometry in some Poisson Manifolds
Abstract: In this talk, we’ll discuss a broad class of Poisson manifolds that are "almost" symplectic in some sense. We’ll first discuss how one can recover a remnant of "symplectic symmetry" inside the tangent algebra via a natural subalgebra that carries a rich algebraic structure. We'll then discuss a long exact sequence linking Poisson cohomology with Lie algebroid cohomology, which computes Poisson Cohomology and clarifies some discrepancies such as those appearing in E-Poisson cohomology. If time permits, we will also describe ongoing work toward assigning harmonic representatives to certain Poisson cohomology classes.
