Abstract

Mathematics Mathematics, Applied Physical Sciences Science & Technology
We review and further develop a general approach to Schur positivity of symmetric functions based on the machinery of noncommutative Schur functions. This approach unifies ideas of Assaf, Lam, and Greene and the second author.
