#### Abstract

A systemic study of some families of -Genocchi numbers and families of polynomials of Nörlund type is presented by using the multivariate fermionic -adic integral on . The study of these higher-order -Genocchi numbers and polynomials yields an interesting -analog of identities for Stirling numbers.

#### 1. Introduction

Let be a fixed odd prime number. Throughout this paper, , and denote the ring of -adic rational integers, the field of -adic rational numbers, the complex number field, and the completion of the algebraic closure of , respectively. Let be the set of natural numbers and . Let be the normalized exponential valuation of with .

When one talks of -extension, is variously considered as an indeterminate, a complex , or a -adic number . If , then one normally assumes . If , then we assume . In this paper, we use the following notation: see [1–10]. Hence for all .

The -factorial is defined as , and the Gaussian binomial coefficient is defined by the standard rule (see [7, 9]). Note that . It readily follows from (1.2) that (see [4, 7]).

For , the -deformed fermionic -adic integral is defined as (see [7, 9]). Note that For , write . Then, we have Using (1.7), we can readily derive the Genocchi polynomials, , namely, (see [1–27]). Note that are referred to as the th Genocchi numbers. Let us now introduce the Genocchi polynomials of Nörlund type as follows: (see [7, 9]). In the special case , and are referred to as the Genocchi numbers of Nörlund type. Let be the shift operator. Then, the -difference operator is defined as (see [4, 7, 9]). It follows from (1.11) that where (see [5, 6, 10]). The -Stirling number of the second kind (as defined by Carlitz) is given by (see [7, 10]). By (1.12) and (1.13), we see that (see [6, 10]).

In this paper, the -extensions of (1.9) are considered in several ways. Using these -extensions, we derive some interesting identities and relations for Genocchi polynomials and numbers of Nörlund type. The purpose of this paper is to present a systemic study of some families -Genocchi numbers and polynomials of Nörlund type by using the multivariate fermionic -adic integral on .

Recently, Kim has studied -adic fermionic integral on connected with the problems of mathematical physics (see [6, 10, 11]), and our result are closely related to his results. In the future, we will try to study -adic stochastic problems associated with our theorems. For example, -adic -Bernstein polynomials seem to be closely related to our results (see [6, 14, 20]).
