The present paper deals with the variousq-Genocchi numbers and polynomials. We define a new type of multiple generalizedq-Genocchi numbers and polynomials with weightαand weak weight
βby applying the method ofp-adic q-integral. We will find a link between their numbers and polynomials with weightαand weak weightβ. Also we will obtain the interesting properties of their numbers and polynomials with weightαand weak weightβ. Moreover, we construct a Hurwitz-type zeta function which interpolates multiple generalizedq-Genocchi polynomials with weightαand weak weightβand find some combinatorial relations.
1. Introduction
Letpbe a fixed odd prime number. Throughout this paperZp,Qp,C, andCpdenote the ring ofp-adic rational integers, the field ofp-adic rational numbers, the complex number field, and the completion of the algebraic closure ofQp, respectively. LetNbe the set of natural numbers andZ N∪ {0}. Letvpbe the normalized exponential valuation ofCpwith|p|p
p−vpp 1/p see1–21. When one talks ofq-extension,qis variously considered as an
indeterminate, a complexq ∈ C, or ap-adic number q ∈ Cp. If q ∈ C, then one normally assumes|q|<1. Ifq∈Cp, then we assume that|q−1|p<1.
Throughout this paper, we use the following notation:
xq 1−q

In the special case x 0,Gn,χr Gn,χr0are called thenth multiple generalized Genocchi

Now, having discussed the multiple generalized Genocchi numbers and polynomials, we were ready to multiple-generalize them to their q-analogues. In generalizing the generating functions of the Genocchi numbers and polynomials to their respective q -analogues; it is more useful than defining the generating function for the Genocchi numbers and polynomialssee12.
Our aim in this paper is to define multiple generalizedq-Genocchi numbersGn,χ,qα,β,rand
polynomials Gn,χ,qα,β,rx with weightαand weak weight β. We investigate some properties
which are related to multiple generalized q-Genocchi numbers Gn,χ,qα,β,r and polynomials
Gn,χ,qα,β,rx with weight α and weak weight β. We also derive the existence of a specific
interpolation function which interpolate multiple generalizedq-Genocchi numbers Gn,χ,qα,β,r
and polynomialsGn,χ,qα,β,rxwith weightαand weak weightβat negative integers.

Many mathematicians constructed various kinds of generating functions of theq-Gnocchi numbers and polynomials by usingp-adicq-Vokenborn integral. First we introduce multiple generalizedq-Genocchi numbers and polynomials with weightαand weak weightβ.
Let us define the generalized q-Genocchi numbersGn,χ,qα,β and polynomials Gn,χ,qα,βx
with weightαand weak weightβ, respectively,

we easily obtainFχt, x.
First, we define the multiple generalizedq-Genocchi numbersGn,χ,qα,β,r with weightα

and Weak Weight
β
In this section, we will investigate about modified multiple generalizedq-Genocchi numbers and polynomials with weight α and weak weight β. Also, we will find their relations in multiple generalizedq-Genocchi numbers and polynomials with weightαand weak weight β.
Firstly, we modify generating functions of Gn,χ,qα,β,r and G α,β,r
n,χ,q x. We access some
relations connected to these numbers and polynomials with weightαand weak weight β. For this reason, we assign generating function of modified multiple generalizedq-Genocchi numbers and polynomials with weightαand weak weightβwhich are implied byGn,χ,qα,β,r
andGn,χ,qα,β,rx. We give relations between these numbers and polynomials with weightαand
weak weightβ.
We modify2.11as follows:
Fα,β,r
χ,q t, x Fχ,qα,β,r
q−αxt, x, 3.1
whereFχ,qα,β,rt, xis defined in2.11.
From the above we know that
Fα,β,r

After some elementary calculations, we attain

whereFχ,qα,β,rtis defined in2.8.
From the above, we can assign the modified multiple generalized q-Genocchi polynomialsεn,χ,qα,β,rxwith weightαand weak weightβas follows:
Fα,β,r

Then we have

By using2.13, we find that
