An Overview of Hopf Algebras of Trees and Their Actions on Functions

Abstract

We provide an expository account of some of the Hopf algebras that can be defined using trees, labeled trees, ordered trees and heap ordered trees. We also describe some actions of these Hopf algebras on algebra of functions.
