A Remmel-Whitney Rule for Quasisymmetric Schur Functions
Remmel and Whitney provided an algorithmic procedure for determining
the Littlewood-Richardson coefficients that appear in the Schur
function expansion of a product of Schur functions. Haglund et
al. introduced the quasisymmetric Schur functions as a basis for
QSym. This paper adapts Remmel and Whitney's approach in order to
determine the coefficients that appear in the quasisymmetric Schur
function expansion of the product of a quasisymmetric Schur function
and a (symmetric) Schur function.
