Skew Divided Difference Operators and Schubert Polynomials
Anatol N. Kirillov Research Institute of Mathematical Sciences (RIMS), Sakyo-ku, Kyoto 606-8502, Japan
Abstract:
We study an action of the skew divided difference operators on the Schubert polynomials and give an explicit formula for structural constants for the Schubert polynomials in terms of certain weighted paths in the Bruhat order on the symmetric group. We also prove that, under certain assumptions, the skew divided difference operators transform the Schubert polynomials into polynomials with positive integer coefficients.
Keywords:
divided differences; nilCoxeter algebras; Schubert polynomials.
