A Littlewood-Richardson Rule for Dual Stable Grothendieck Polynomials

Published 31 Dec 2014 in math.CO | (1501.00051v2)

Abstract: For a given skew shape, we build a crystal graph on the set of all reverse plane partitions that have this shape. As a consequence, we get a simple extension of the Littlewood-Richardson rule for the expansion of the corresponding dual stable Grothendieck polynomial in terms of Schur polynomials.
