#### Abstract

A systemic study of some families of the modified -Bernoulli numbers and polynomials with weight is presented by using the -adic -integration . The study of these numbers and polynomials yields an interesting -analogue related to Bernoulli numbers and polynomials.

#### 1. Introduction

Let be a fixed prime number. Throughout this paper , and will, respectively, denote the ring of -adic rational integers, the field of -adic rational numbers, the complex number field, and the completion of the algebraic closure of . Let be the normalized exponential valuation of with . When one talks of -extension, is variously considered as an indeterminate, a complex , or a -adic number . If , one normally assumes . If , then we assume so that for .

The -number is defined by see [110].

We say that is a uniformly differentiable function at a point and denote this property by , if the difference quotients have a limit as . c.f. [11].

For , the -adic -integral on is defined by (see [3]).

From (1.3), we can easily derive the following: where , (see [5, 12]).

In [1, 2], Carlitz defined a set of numbers inductively by with the usual convention about replacing by .

These numbers are the -extension of ordinary Bernoulli numbers. But they do not remain finite when . So, Carlitz modified (1.5) as follows: with the usual convention of replacing by .

In [1], Carlitz also considered the extension of Carlitz’s -Bernoulli numbers as follows: with the usual convention of replacing by .

In this paper, we construct the modified -Bernoulli numbers with weight , which are different Carlitz’s -Bernoulli numbers, by using -adic -integral equation. From (1.4), we derive some interesting identities and relations on the modified -Bernoulli numbers and polynomials.
