Description: |
Symplectic groupoids are geometric objects that function as global counterparts to Poisson manifolds, in the same way that Lie groups are global counterparts to Lie algebras.
In this talk I will first give an idea of how that analogy works, and I will present the construction of the deformation cohomology controlling deformations of symplectic groupoids.
I will then compute this cohomology in some examples, explain how to use it in a Moser path argument, and relate it to the deformation theory of the corresponding Poisson manifolds.
The talk is based on joint work with Cristian Cárdenas (UFF) and Ivan Struchiner (USP).
