A Lift of the Schur and Hall-Littlewood Bases to Non-commutative Symmetric Functions
We introduce a new basis of the algebra of non-commutative symmetric functions whose images under the forgetful map are Schur functions when indexed by a partition. Dually, we build a basis of the quasi-symmetric functions which expand positively in the fundamental quasi-symmetric functions. We then use the basis to construct a non-commutative lift of the Hall-Littlewood symmetric functions with similar properties to their commutative counterparts.

Keywords:Hall-Littlewood polynomial, symmetric function, quasisymmetric function, tableau
