Decomposable Compositions, Symmetric Quasisymmetric Functions and Equality of Ribbon Schur Functions
2005
LOUIS J. BILLERA
STEPHANIE VAN WILLIGENBURG
We define an equivalence relation on integer compositions and show that two ribbon Schur functions are identical if and only if their defining compositions are equivalent in this sense. This equivalence is completely determined by means of a factorization for compositions: equivalent compositions have factorizations that differ only by reversing some of the terms. As an application, we can deri...
