Tuesday, 12 April 2016, 3 p.m. (sharp), Prof. Lorenzo Zambotti, UPMC Parigi, at the conference room of Dipartimento di Matematica in Pavia (aula Beltrami), will give a lecture titled:

RENORMALISATION IN REGULARITY STRUCTURES

as part of the Applied Mathematics Seminar (IMATI-CNR e Dipartimento di Matematica, Pavia).
At the end a refreshment will be organized.

Abstract.

In this talk we want to present a detailed study of the algebraic objects appearing in the theory of regularity structures. In particular we aim at introducing a class of co-algebras on labelled forests and trees and show that these allow to describe in a unified setting the structure group and the renormalisation group.
Based on joint work with Yvain Bruned and Martin Hairer.
