#### Abstract

The purpose of this paper is to give some properties of the modified -Bernoulli numbers and polynomials of higher order with weight. In particular, by using the bosonic -adic -integral on , we derive new identities of -Bernoulli numbers and polynomials with weight.

#### 1. Introduction

Let be a fixed odd prime number. Throughout this paper , and will, respectively, denote the ring of -adic rational integers, the field of -adic rational numbers, and the completion of the algebraic closure of . Let be the set of natural numbers and . The -adic norm of is defined by . When one talks of a -extension, can be considered as an indeterminate, a complex number , or a -adic number . Throughout this paper we assume that and with so that .

Let be the space of uniformly differentiable functions on . For , the -adic -integral on is defined by Kim (see [1β3]) as follows: where is the -number of which is defined by .

From (1.1), we have where (see [2β4]).

As is well known, Bernoulli numbers are inductively defined by with the usual convention about replacing by (see [3, 5]).

In [2, 5, 6], the -Bernoulli numbers are defined by with the usual convention about replacing by . Note that . In the viewpoint of (1.4), we consider the modified -Bernoulli numbers with weight.

In this paper we study families of the modified -Bernoulli numbers and polynomials of higher order with weight. In particular, by using the multivariate -adic -integral on , we give new identities of the higher-order -Bernoulli numbers and polynomials with weight.

#### 2. Modified -Bernoulli Numbers with Weight of Higher Order

For , let us consider the following modified -Bernoulli numbers with weight (see [1, 3]): From (2.1), we note that (see [1, 3]).

For and , by making use of the multivariate -adic -integral on , we consider the following modified -Bernoulli numbers with weight of order , : Note that and , where are the th ordinary Bernoulli numbers of order .

For , we have By (1.1), (2.3), and (2.4), we get Therefore, by (2.5), we obtain the following theorem.

Theorem 2.1. *For , one has
*

Let us consider the modified -Bernoulli and polynomials with weight of order as follows: By the same method of (2.5), we obtain the following theorem.

Theorem 2.2. *For , one has
*

By Theorem 2.2, we get Therefore, by (2.9), we obtain the following theorem.

Theorem 2.3. *For , one has
*

From Theorem 2.3, we note that Thus, we have , where are the th Bernoulli numbers of order .

From (2.3) and (2.7), we can derive the following equations: Therefore, by (2.12), we obtain the following theorem.

Theorem 2.4. *For and , one has
*

In particular,

From (1.2), we can derive the following integral: Continuing this process, we obtain By (2.16), we get Therefore, by (2.1) and (2.17), we obtain the following theorem.

Theorem 2.5. *For and , one has
*

In an analogues manner as the previous investigation [7β10], we can define a further generalization of modified -Bernoulli numbers with weight. Let be the Dirichlet character with conductor . Then the generalized -Bernoulli numbers with weight attached to can be defined as follows: We expect to investigate these objects in future papers. This definition was also given in a previous paper (see [9]).
