#### Abstract

Recently many mathematicians are working on Genocchi polynomials and Genocchi numbers. We define a new type of twisted *q*-Genocchi numbers and polynomials with weight and weak weight and give some interesting relations of the twisted *q*-Genocchi numbers and polynomials with weight and weak weight . Finally, we find relations between twisted *q*-Genocchi zeta function and twisted Hurwitz *q*-Genocchi zeta function.

#### 1. Introduction

The Genocchi numbers and polynomials possess many interesting properties and arising in many areas of mathematics and physics. Recently, many mathematicians have studied in the area of the -Genocchi numbers and polynomials (see [1â€“16]).

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 assume that so that for . Throughout this paper we use the following notation: (cf. [1â€“13]).

Hence, for any with in the present -adic case.

For the fermionic -adic -integral on is defined by Kim as follows: (cf. [11â€“14]).

If we take in (1.1), then we easily see that From (1.4), we obtain where (cf. [5â€“9]).

Let be the cyclic group of order and let be the locally constant space. For , we denote by the locally constant function .

As well-known definition, the Genocchi polynomials are defined by with the usual convention of replacing by . are called the th Genocchi numbers (cf. [2â€“5, 14]).

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 twisted -Genocchi numbers and polynomials with weight and weak weight . We investigate some properties which are related to and . We also derive the existence of a specific interpolation function which interpolate and at negative integers.
