In this paper, we report on recent progress concerning combinatorial aspects of normal
ordering. After giving a short introduction to the history and motivation of normal ordering, we …

In this paper, a q-analogue of r-Whitney-Lah numbers, also known as (q, r)-Whitney-Lah
number, denoted by $ L_ {m, r}[n, k] _q $ is defined using the triangular recurrence relation …

In this paper,(p, q)-analogues of r-Whitney numbers of the first and second kinds are defined
using horizontal generating functions. Several fundamental properties such as orthogonality …

In this paper, the Hankel transform of the generalized q-exponential polynomial of the first
form (q, r)-Whitney numbers of the second kind is established using the method of Cigler …
