# Multivariate Twisted -Adic -Integral on Associated with Twisted -Bernoulli Polynomials and Numbers

## Abstract

Recently, many authors have studied twisted -Bernoulli polynomials by using the -adic invariant -integral on . In this paper, we define the twisted -adic -integral on and extend our result to the twisted -Bernoulli polynomials and numbers. Finally, we derive some various identities related to the twisted -Bernoulli polynomials.

## 1. Introduction

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

When one talks of -extension, is variously considered as an indeterminate, a complex or -adic number If one normally assumes that If then we assume that .

When and the polynomials and numbers are called the twisted Bernoulli polynomials and numbers, respectively. When and the polynomials and numbers are called the ordinary Bernoulli polynomials and numbers, respectively.

Many authors have studied the twisted -Bernoulli polynomials by using the properties of the -adic invariant -integral on (cf. [4]). In this paper, we define the twisted -adic -integral on and extend our result to the twisted -Bernoulli polynomials and numbers. Finally, we derive some various identities related to the twisted -Bernoulli polynomials.

(2.10)

We have
