Recently, the generalized Euler–Genocchi and degenerate polynomials are introduced. The aim of this note is to study multi-Euler–Genocchi which defined by means multiple logarithm generalize, respectively, polynomials. Especially, we express former polynomials, multi-Stirling numbers first kind Stirling second kind, latter kind.

The Jacobi-Stirling numbers of the first and second kind were introduced in 2007 by Everitt et al. In this article we find new explicit formulas for Jacobi Stirling numbers. Furthermore, derive study class so-called generalized Some special cases such as Legendre-Stirling are given. interesting combinatorial identities obtained.

Multirestricted Stirling numbers of the second kind count the number of partitions of a given set into a given number of parts, each part being restricted to at most a fixed number of elements. Multirestricted numbers of the first kind are then defined as elements of the matrix inverse to the matrix of corresponding multirestricted numbers of the second kind. The anomalous sign behavior of thes...

The Jacobi-Stirling numbers of the first and second kinds were introduced in 2006 in the spectral theory and are polynomial refinements of the Legendre-Stirling numbers. Andrews and Littlejohn have recently given a combinatorial interpretation for the second kind of the latter numbers. Noticing that these numbers are very similar to the classical central factorial numbers, we give combinatorial...
