Résumé : The theory of commutative symmetric functions started centuries ago with elementary symmetric functions: coefficients of a generic polynomial can be written as symmetric functions on its roots. I will describe a noncommutative generalization of this theorem and use it as the foundation of a theory of noncommutative symmetric functions.
