#### Abstract

We define the multiple generalized -Genocchi polynomials. By using fermionic -adic invariant integrals, we derive some identities on these generalized -Genocchi polynomials, for example, fermionic -adic integral representation, Witt's type formula, explicit formula, multiplication formula, and recurrence formula for these -Genocchi polynomials.

#### 1. Introduction

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

The -basic natural numbers are defined by for , and the binomial coefficient is defined as The binomial formulas are well known that (see, [1, 2]). When one talks of -extension, is variously considered as an indeterminate, a complex number , or a -adic number . If , one normally assumes that . If , one normally assumes that . We use the notation see [1–13] for all . Note that for in presented -adic case.

Let be denoted by the set of uniformly differentiable function on . For , an invariant -adic -integral on is defined as Thus, we have the following integral relation: where , and the fermionic -adic invariant integral relation:

Now, we recall that the definitions of -Euler polynomials and -Genocchi polynomials are defined as with , respectively. In the special case , , and are called -Euler numbers and -Genocchi numbers (see [2, 9]).

In [13], Bayard and Simsek have studied multiple generalized Bernoulli polynomials as follows: where are strictly positive real numbers.

The purpose of this paper is to define another construction of multiple generalized -Genocchi polynomials and numbers, which are different from multiple generalized Bernoulli polynomials and numbers in [13]. By using fermionic -adic invariant integrals, we derive some identities on these generalized -Genocchi polynomials, for example, fermionic -adic integral representation, Witt's type formula, explicit formulas, multiplication formula, and recurrence formula for these -Genocchi polynomials.

#### 2. Multiple Generalized -Genocchi Polynomials and Numbers

Let and be strictly positive real numbers. The multiple generalized -Genocchi polynomials are defined as where . The values of at are called the multiple generalized -Genocchi numbers: when , , and (), the polynomials or numbers are called the ordinary Genocchi polynomials or numbers.

It is known that

For any , we can directly derive the following equation: By comparing the coefficients on both sides in (2.18), we obtain the recurrence formula for the multiple generalized -Genocchi polynomials.
