#### Abstract

We construct a new type of -Genocchi numbers and polynomials with weight and weak weight , respectively. Some interesting results and relationships are obtained.

#### 1. Introduction

The Genocchi numbers and polynomials possess many interesting properties and are arising in many areas of mathematics and physics. Recently, many mathematicians have studied in the area of the -Genocchi numbers and polynomials (see [1β13]). In this paper, we construct a new type of -Genocchi numbers and polynomials with weight and weak weight .

Throughout this paper, we use the following notations. By , we denote the ring of -adic rational integers, denotes the field of -adic rational numbers, denotes the completion of algebraic closure of , denotes the set of natural numbers, denotes the ring of rational integers, denotes the field of rational numbers, denotes the set of complex numbers, and . Let be the normalized exponential valuation of with . When one talks of -extension, is considered in many ways such as an indeterminate, a complex number , or -adic number . If , one normally assume that . If , we normally assumes that so that for . Throughout this paper, we use the notation cf. [1β13].

Hence, for any with in the present -adic case. For the fermionic -adic -integral on is defined by Kim as follows: cf. [3β6].

If we take in (1.1), then we easily see that From (1.4), we obtain where (cf. [3β6]).

As-well-known definition, the Genocchi polynomials are defined by with the usual convention of replacing by . In the special case, , are called the -th Genocchi numbers (cf. [1β11]).

These numbers and polynomials are interpolated by the Genocchi zeta function and Hurwitz-type Genocchi zeta function, respectively. Our aim in this paper is to define -Genocchi numbers and polynomials with weight and weak weight . We investigate some properties which are related to -Genocchi numbers and polynomials with weight and weak weight . We also derive the existence of a specific interpolation function which interpolates -Genocchi numbers and polynomials with weight and weak weight at negative integers.

By using -Genocchi numbers and polynomials with weight and weak weight , -Genocchi zeta function and Hurwitz -Genocchi zeta functions are defined. These functions interpolate the -Genocchi numbers and -Genocchi polynomials with weight and weak weight , respectively. In this section, we assume that with . From (2.4), we note that By using the above equation, we are now ready to define -Genocchi zeta functions.
