On xD-Generalizations of Stirling Numbers and Lah Numbers via Graphs and Rooks

Sen-Peng Eu, Tung-Shan Fu, Yu-Chang Liang +1

This paper studies the generalizations of the Stirling numbers of both kinds and the Lah numbers in association with the normal order problem in the Weyl algebra $W=\langle x,D|Dx-…

The sorting index on colored permutations and even-signed permutations

Sen-Peng Eu, Yuan-Hsun Lo, Tsai-Lien Wong

We define a new statistic $sor$ on the set of colored permutations $G_{r, n}$ and prove that it has the same distribution as the length function. For the set of re…

Set-valued sorting index and joint equidistributions

Sen-Pen Eu, Yuan-Hsun Lo, Tsai-Lien Wong

Recently Petersen defined a new Mahonian index sor over the symmetric group $S_{n}$ and proved that $(inv, rlmin)$ and $(sor, cyc)$ have the sa…

Hankel determinants of sums of consecutive weighted Schröder numbers

Sen-Peng Eu, Tsai-Lien Wong, Pei-Lan Yen

For a real number $t$ , let $r_{ℓ} (t)$ be the total weight of all $t$ -large Schröder paths of length $ℓ$ , and $s_{ℓ} (t)$ be the total weight of all $t$ -small Schröder paths of…
