摘要

根据费罗尼和拉尔森的研究成果，完整图的卡兹丹-卢兹提格多项式和 Z 多项式可以用准数列平行矩阵来组合解释。我们提供了给定秩和心数的数列平行矩阵数和简单数列平行矩阵数的明确公式，扩展了费罗尼-拉森和高-普鲁福-杨-张的结果。

On the enumeration of series-parallel matroids

By the work of Ferroni and Larson, Kazhdan–Lusztig polynomials and Z-polynomials of complete graphs have combinatorial interpretations in terms of quasi series-parallel matroids. We provide explicit formulas for the number of series-parallel matroids and the number of simple series-parallel matroids of a given rank and cardinality, extending results of Ferroni–Larson and Gao–Proudfoot–Yang–Zhang.
