Abstract
The descent polynomial of a finite I ⊆ Z + is the polynomial d(I, n), for which the evaluation at n > max(I) is the number of permutations on n elements, such that I is the set of indices where the permutation is descending. In this paper we will prove some conjectures concerning coefficient sequences of d(I, n). As a corollary we will describe some zero-free regions for the descent polynomial.
