#### Abstract

We consider the weighted -Genocchi numbers and polynomials. From the construction of the weighted -Genocchi numbers and polynomials, we investigate many interesting identities and relations satisfied by these new numbers and polynomials.

#### 1. Introduction

Let be a fixed odd prime number. Throughout this paper, , , , and , will, respectively, denote the ring of -adic integers, the field, of -adic rational numbers, the complex number field and the completion of algebraic closure of . Let be the normalized exponential valuation of such that (see [116]).

As well-known definition, the Euler numbers and Genocchi numbers are defined by with the usual convention of replacing by and with the usual convention of replacing by . We assume that with and that the -number of is defined by (see [119]).

In [9], Kim introduced ordinary fermionic -adic integral on , and he studied some interesting relations and identities related to -extension of Euler numbers and polynomials. In [8], he also introduced the -extension of the ordinary fermionic -adic integral on and he investigated many physical properties related to -Euler numbers and polynomials. Recently, Kim firstly introduced the meaning of the weighted -Euler numbers and polynomials associated with the weighted -Bernstein polynomials by using the fermionic invariant -adic integral on (see [14, 15]). In [16], Ryoo tried to study the weighted -Euler number and polynomials by the same method of Kim et al. in [14] and the -extension of the fermionic -adic invariant integrals on . As well-known properties, the Genocchi numbers are integers. The first few Genocchi numbers for are . The first few prime Genocchi numbers are −3 and 17, which occur for and 8. There are no others with . These properties are very important to study in the area of fermionic distribution and -adic numbers theory. By this reason, many mathematicians and physicians have studied Genocchi and Euler numbers which are in the different areas. By the same motivation, we consider weighted -Genocchi polynomials and numbers by using the fermionic -adic -integral on which are constructed by Kim and Ryoo (cf. [8, 16]).

In this paper, we consider the -Genocchi numbers and polynomials with weighted . From the construction of the weighted -Genocchi numbers and polynomials, we investigate many interesting identities and relations satisfied by these new numbers and polynomials.
