The descent polynomial of a finite is the polynomial , for which the evaluation at is the number of permutations on elements, such that is the set of indices where the permutation is descending. In this paper, we will prove some conjectures concerning coefficient sequences of . As a corollary, we will describe some zero-free regions for the descent polynomial.

一些与下降多项式相关的系数序列
有限元的下降多项式 是多项式 ,其中评估在 是排列的数量 元素,使得 是排列下降的索引集。在本文中,我们将证明一些关于系数序列的猜想. 作为推论,我们将描述下降多项式的一些无零区域。
