A non-commutative generalization of $k$-Schur functions

Combinatorics 2016-11-08 v1

Abstract

We introduce non-commutative analogues of kk-Schur functions of Lapointe-Lascoux and Morse. We give an explicit formulas for the expansions of non-commutive functions with one and two parameters in terms of these new functions. These results are similar to the conjectures existing in the commutative case.
