Total positivity of matrices is deeply studied and plays an important role in various branches of mathematics. The aim of this paper is to study the criteria for coefficientwise Ha…
Stability of combinatorial polynomials and its applications
Ming-Jian Ding, Bao-Xuan Zhu
The aim of this paper is to make a systematical study on the stability of polynomials in combinatorics. Applying the characterizations of Borcea and Brändén concerning linear opera…
On a Stirling-Whitney-Riordan triangle
Bao-Xuan Zhu
Based on the Stirling triangle of the second kind, the Whitney triangle of the second kind and one triangle of Riordan, we study a Stirling-Whitney-Riordan triangle $[T_{n,k}]_{n,k…
A unified approach to combinatorial triangles: a generalized Eulerian polynomial
Bao-Xuan Zhu
Motivated by the classical Eulerian number, descent and excedance numbers in the hyperoctahedral groups, an triangular array from staircase tableaux and so on, we study a triangula…
Stieltjes moment properties and continued fractions from combinatorial triangles
Bao-Xuan Zhu
Many combinatorial numbers can be placed in the following generalized triangular array satisfying the recurrence relation: \begin{equation*} T_{n,k}=λ(a_0n+a…
