Some Hecke Algebra Products and Corresponding Random Walks

Rosena R. X. Du, Richard P. Stanley

Let $i = 1 + q + ... + q^{i - 1}$ . For certain sequences $(r_{1}, ..., r_{l})$ of positive integers, we show that in the Hecke algebra $H_{n} (q)$ of the symmetric group $\mathfrak{S}_…

(k,m)-Catalan Numbers and Hook Length Polynomials for Plane Trees

Rosena R. X. Du, Fu Liu

Motivated by a formula of A. Postnikov relating binary trees, we define the hook length polynomials for m-ary trees and plane forests, and show that these polynomials have a simple…
