AN OVERVIEW OF Λ-TYPE OPERATIONS ON QUASI-SYMMETRIC FUNCTIONS

Abstract

We present an overview of Λ-type operations on the algebra of quasi-symmetric functions.

Nous présentons un survol de l'ensemble des propriétés de type Λ-anneau de l'algèbre des fonctions quasi-symétriques.

^*Notice that n and m are not defined as in the previous section, since they do not play the same role if one considers the quasi-monomial functions or the quasi-ribbon functions.
