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.
