Non-commutative symmetric functions
For an introduction to non-commutative symmetric functions, we refer to [GKLLRT95].
The non-commutative symmetric functions are dual to the quasisymmetric functions. These are not to be confused with symmetric functions in non-commutative variables.
Non-commutative Schur functions
See [GKLLRT95] for definition of the non-commutative Schur polynomials.
See [Tew16] for a non-commutative lifting of the classical Murnaghan–Nakayama rule.
