摘要

最近，Cheng 等人 (2023) [7]将反转数推广到局部排列（也称为拉盖尔数图），并要求找到一个合适的类似于 MacMahon 的主要指数。我们提供了这样一种主要指数，即相应的 maj 和 inv 统计量是等分布的，并表现出 Haglund-Remmel-Wilson 类型的特性。然后，我们用拉盖尔数图解释了一些雅各布-罗杰斯多项式，推广了 Deb 和 Sokal 对一些特殊雅各布-罗杰斯多项式的交替拉盖尔数图解释。

Mahonian-Stirling statistics for partial permutations

Recently Cheng et al. (2023) [7] generalized the inversion number to partial permutations, which are also known as Laguerre digraphs, and asked for a suitable analogue of MacMahon's major index. We provide such a major index, namely, the corresponding maj and inv statistics are equidistributed, and exhibit a Haglund-Remmel-Wilson type identity. We then interpret some Jacobi-Rogers polynomials in terms of Laguerre digraphs generalizing Deb and Sokal's alternating Laguerre digraph interpretation of some special Jacobi-Rogers polynomials.
