一类Hecke代数积及其随机游动

Some Hecke Algebra Products and Corresponding Random Walks

Rosena R. X. Du, Richard P. Stanley

摘要:

令$\bm{i}=1+q+...+q^{i-1}$。对某些正整数序列$(r_1,...,r_l)$,我们证明了在对称群$\mathfrak{S}_n$的Hecke代数$\mathscr{H}_n(q)$中,乘积$(1+\bm{r_1}T_{r_1})... (1+\bm{r_l}T_{r_l})$关于标准基$\{T_w\}$有一个简单的显式展开.给出了解释的随机游动$\mathfrak{S}_n$。

英文摘要:

Let $\bm{i}=1+q+...+q^{i-1}$. For certain sequences $(r_1,...,r_l)$ of positive integers, we show that in the Hecke algebra $\mathscr{H}_n(q)$ of the symmetric group $\mathfrak{S}_n$, the product $(1+\bm{r_1}T_{r_1})... (1+\bm{r_l}T_{r_l})$ has a simple explicit expansion in terms of the standard basis $\{T_w\}$. An interpretation is given in terms of random walks on $\mathfrak{S}_n$.
