交替符号矩阵与全对称平面分拆

Alternating sign matrices and totally symmetric plane partitions

Florian Aigner, Ilse Fischer, Matjaž Konvalinka, Philippe Nadeau, Vasu Tewari

摘要:

本文研究了一类对称多项式的Schur多项式展开式,它涉及交替符号矩阵关于其逆数、互补逆数和唯一$1$在顶行的位置的精化计数.我们证明了扩展可以表示为一个总和在完全对称的平面分区,我们也能够确定的系数。这建立了交替符号矩阵和一类平面分区之间的新联系,从而补充了交替符号矩阵与完全对称自互补平面分区以及下降平面分区相等的事实。作为一个副产品,我们得到一个有趣的映射,从完全对称的平面分区到Dyck路径。证明是基于一个新的,相当一般的反对称化子行列式公式。

英文摘要:

We study the Schur polynomial expansion of a family of symmetric polynomials related to the refined enumeration of alternating sign matrices with respect to their inversion number, complementary inversion number and the position of the unique $1$ in the top row. We prove that the expansion can be expressed as a sum over totally symmetric plane partitions and we are also able to determine the coefficients. This establishes a new connection between alternating sign matrices and a class of plane partitions, thereby complementing the fact that alternating sign matrices are equinumerous with totally symmetric self-complementary plane partitions as well as with descending plane partitions. As a by-product we obtain an interesting map from totally symmetric plane partitions to Dyck paths. The proof is based on a new, quite general antisymmetrizer-to-determinant formula.
