Proof of a nonnegativity conjecture of Prellberg--Stanton

Hong-Zhang Ai, Lili Mu, Bao-Xuan Zhu

In 1994, Friedman, Joichi and Stanton conjectured that coefficients of the power-series $q + (1 - q) \prod_{i = n}^{2 n - 1} \frac{1}{1 - q ^{i}}$ are nonnegative for $n \geq 3$ and $n$ being odd.…

Yet another criterion for the total positivity of Riordan arrays

Jianxi Mao, Lili Mu, Yi Wang

Let $R = R (d (t), h (t))$ be a Riordan array, where $d (t) = \sum_{n \geq 0} d_{n} t^{n}$ and $h (t) = \sum_{n \geq 0} h_{n} t^{n}$ . We show that if the matrix \begin{equation*} \left[\begin{array}…

Catalan-like numbers and Stieltjes moment sequences

Huyile Liang, Lili Mu, Yi Wang

We provide sufficient conditions under which the Catalan-like numbers are Stieltjes moment sequences. As applications, we show that many well-known counting coefficients, including…

Supersolvability and Freeness for $ψ$ -graphical Arrangements

Lili Mu, Richard P. Stanley

Let $G$ be a simple graph on the vertex set ${v_{1}, \dots, v_{n}}$ with edge set $E$ . Let $K$ be a field. The graphical arrangement $A_{G}$ in $K^{n}$ is the arrangement $x_i-x_…
