Weekly seminar of AG Laboratory: Pavel Safronov (Geneva)

Pavel Safronov (Geneva) with the talk Introduction to derived Poisson geometry with examples

Derived Poisson geometry studies higher Poisson structures on (derived) algebraic stacks. I will explain what higher Poisson structures are and how to define them on stacks following the work of Calaque, Pantev, Toen, Vaqui'e and Vezzosi. Moreover, one can define an interesting generalization of the notion of a coisotropic submanifold in this context which I will describe following joint work with Melani. In the second half of the talk I will give several examples of these constructions some of which come from Poisson-Lie groups.
