任意直线下路的混洗定理

A Shuffle Theorem for Paths Under Any Line

Jonah Blasiak, Mark Haiman, Jennifer Morse, Anna Pun, George H. Seelinger

摘要:

我们推广了Haglund等人和Bergeron等人提出的洗牌定理及其$(km,kn)$版本,并分别由Carlsson和Mellit以及Mellit证明。在我们的版本中的组合侧的$(km,kn)$ Dyck路径被替换为格路径躺在线段的$x$和$y$截距不需要是整数,和代数侧是由Schiffmann代数算子公式或一个等效的明确提高运营商公式。我们推导出我们的组合身份的多项式截断的身份的无限系列的$GL_{l}$字符,表示在无穷级数版本的LLT多项式。这个级数恒等式是由非对称霍尔-利特尔伍德多项式的柯西恒等式得到的。

英文摘要:

We generalize the shuffle theorem and its $(km,kn)$ version, as conjectured by Haglund et al. and Bergeron et al., and proven by Carlsson and Mellit, and Mellit, respectively. In our version the $(km,kn)$ Dyck paths on the combinatorial side are replaced by lattice paths lying under a line segment whose $x$ and $y$ intercepts need not be integers, and the algebraic side is given either by a Schiffmann algebra operator formula or an equivalent explicit raising operator formula. We derive our combinatorial identity as the polynomial truncation of an identity of infinite series of $GL_{l}$ characters, expressed in terms of infinite series versions of LLT polynomials. The series identity in question follows from a Cauchy identity for non-symmetric Hall-Littlewood polynomials.
