seminar: Global formality at the G_infty level

speaker: Michel van den Bergh (Universiteit Hasselt)

abstract: It has been proved by Dolgushev, Tamarkin and Tsygan that the sheaf of polydifferential operators on a smooth scheme is formal as a sheaf of G_infty algebras. We discuss a different proof of this fact. This is joint work with Damien Calaque.
