We introduce non-commutative analogs of k-Schur functions of Lapointe-Lascoux and Morse. We give explicit formulas for the expansions of non-commutative functions with one and two parameters in terms of these new functions. These results are similar to the conjectures existing in the commutative case. (C) 2009 Elsevier B.V. All rights reserved.
