## 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.

\todo Define non-commutative analogues of symmetric functions. }## Non-commutative Schur functions

See [GKLLRT95] for definition of the non-commutative Schur polynomials.

## Murnaghan–Nakayama rule

See [Tew16] for a non-commutative lifting of the classical Murnaghan–Nakayama rule.
