关于计数满填充环组态的多项式

On some polynomials enumerating Fully Packed Loop configurations

Tiago Fonseca, Philippe Nadeau

摘要:

我们感兴趣的是在一个给定的非交叉匹配的网格上的完全填充回路配置的枚举。通过最近证明的Razumov-Stroganov猜想,这些量也出现在完全填充环模型中的基态分量。当考虑匹配与p嵌套拱,这些数字是已知的多项式在p中。在这篇文章中,我们提出了几个关于这些多项式的abstitures:特别是,我们描述了所有的实根,这些多项式的某些值,并推测系数是积极的。的结构,这是一个组合的性质,支持强有力的数值证据和几个特殊情况下的证明。我们还给出了在定义完全填充环模型基态的方程中加入一个额外参数τ时的一个版本的结构。

英文摘要:

We are interested in the enumeration of Fully Packed Loop configurations on a grid with a given noncrossing matching. By the recently proved Razumov--Stroganov conjecture, these quantities also appear as groundstate components in the Completely Packed Loop model. When considering matchings with p nested arches, these numbers are known to be polynomials in p. In this article, we present several conjectures about these polynomials: in particular, we describe all real roots, certain values of these polynomials, and conjecture that the coefficients are positive. The conjectures, which are of a combinatorial nature, are supported by strong numerical evidence and the proofs of several special cases. We also give a version of the conjectures when an extra parameter tau is added to the equations defining the groundstate of the Completely Packed Loop model.
