A combinatorial Hopf algebra for the boson normal ordering problem
Imad Eddine Bousbaa, Ali Chouria, Jean-Gabriel Luque
In the aim to understand the generalization of Stirling numbers occurring in the bosonic normal ordering problem, several combinatorial models have been proposed. In particular, Bl…
Combinatorial approach of certain generalized Stirling numbers
Hacène Belbachir, Amine Belkhir, Imad Eddine Bousbaa
A combinatorial methods are used to investigate some properties of certain generalized Stirling numbers, including explicit formula and recurrence relations. Furthermore, an expres…
Associated Lah numbers and r-Stirling numbers
Hacene Belbachir, Imad Eddine Bousbaa
We introduce the associated Lah numbers. Some recurrence relations and convolution identities are established. An extension of the associated Stirling and Lah numbers to the r-Stir…
