Macdonald多项式的矩阵积和法则

Matrix product and sum rule for Macdonald polynomials

Luigi Cantini, Jan de Gier, Michael Wheeler

摘要:

我们提出了一个新的,明确的和公式的对称麦克唐纳多项式$P_λ$,并表明,他们可以被写为一个产品(无限维)矩阵的迹。这些矩阵满足Zamolodchikov-Faddeev(ZF)代数。我们构造的ZF代数的解决方案,从一个降秩版本的杨-巴克斯特代数。作为推论,我们发现多种群非对称排它过程的平稳测度的归一化是一个所有变量都等于1的Macdonald多项式。

英文摘要:

We present a new, explicit sum formula for symmetric Macdonald polynomials $P_λ$ and show that they can be written as a trace over a product of (infinite dimensional) matrices. These matrices satisfy the Zamolodchikov--Faddeev (ZF) algebra. We construct solutions of the ZF algebra from a rank-reduced version of the Yang--Baxter algebra. As a corollary, we find that the normalization of the stationary measure of the multi-species asymmetric exclusion process is a Macdonald polynomial with all variables set equal to one.
