The 1/k-Eulerian polynomials and k-Stirling permutations
Shi-Mei Ma, Toufik Mansour
In this paper, we establish a connection between the 1/k-Eulerian polynomials introduced by Savage and Viswanathan (Electron. J. Combin. 19(2012), P9) and k-Stirling permutations.…

Some combinatorial arrays related to the Lotka-Volterra system
Shi-Mei Ma, Toufik Mansour, David Callan
The purpose of this paper is to investigate the connection between the Lotka-Volterra system and combinatorics. We study several context-free grammars associated with the Lotka-Vol…

Several variants of the Dumont differential system and permutation statistics
Shi-Mei Ma, Toufik Mansour, David G. L. Wang +1
The Dumont differential system on the Jacobi elliptic functions was introduced by Dumont (Math Comp, 1979, 33: 1293--1297) and was extensively studied by Dumont, Viennot, Flajolet…
