The reduced phase space of the Poisson Sigma Model (PSM) comes equipped with a symplectic groupoid structure, when the worldsheet is a disk and the target Poisson structure is integrable. In this talk we describe an extension of this construction when we consider surfaces with arbitrary genus, obtaining the abelianization of the original groupoid. We will also describe the obstructions for... More >
