Coxeter-Knuth graphs and a signed Little map for type B reduced words

Sara Billey, Zachary Hamaker, Austin Roberts +1

We define an analog of David Little's algorithm for reduced words in type B, and investigate its main properties. In particular, we show that our algorithm preserves the recording…

On the Schur expansion of Hall-Littlewood and related polynomials via Yamanouchi words

Austin Roberts

This paper uses the theory of dual equivalence graphs to give explicit Schur expansions for several families of symmetric functions. We begin by giving a combinatorial definition o…
