## Abstract

We study the symmetry for the generalized twisted Bernoulli polynomials and numbers. We give some interesting identities of the power sums and the generalized twisted Bernoulli polynomials using the symmetric properties for the -adic invariant integral.

## 1. Introduction

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

Let be the space of uniformly differentiable function on . For , the -adic invariant integral on is defined as

(see [1]). From (1.1), we note that

where and . For , let . Then we can derive the following equation from (1.2):

Let be a fixed positive integer. For , let

The ordinary Bernoulli polynomials are defined as

and the Bernoulli numbers are defined as (see [1â€“19]).

For , let be the -adic locally constant space defined by

where is the cyclic group of order . It is well known that the twisted Bernoulli polynomials are defined as

and the twisted Bernoulli numbers are defined as (see [15â€“18]).

Let be Dirichlet's character with conductor . Then the generalized twisted Bernoulli polynomials attached to are defined as follows:

The generalized twisted Bernoulli numbers attached to , , are defined as (see [16]).

Recently, many authors have studied the symmetric properties of the -adic invariant integrals on , which gave some interesting identities for the Bernoulli and the Euler polynomials (cf. [3, 6, 7, 13, 14, 20â€“27]). The authors of this paper have established various identities by the symmetric properties of the -adic invariant integrals and investigated interesting relationships between the power sums and the Bernoulli polynomials (see [2, 3, 6, 7, 13]).

The twisted Bernoulli polynomials and numbers and the twisted Euler polynomials and numbers are very important in several fields of mathematics and physics(cf. [15â€“18]). The second author has been interested in the twisted Euler numbers and polynomials and the twisted Bernoulli polynomials and studied the symmetry of power sum and twisted Bernoulli polynomials (see [11â€“13]).

The purpose of this paper is to study the symmetry for the generalized twisted Bernoulli polynomials and numbers attached to . In Section 2, we give interesting identities for the power sums and the generalized twisted Bernoulli polynomials using the symmetric properties for the -adic invariant integral.

## 2. Symmetry for the Generalized Twisted Bernoulli Polynomials

Let be Dirichlet's character with conductor . For , we have

By (2.1) and (2.2), we see that

From (2.3), we derive that

By (1.5) and (2.3), we see that

From (2.2) and (2.5), we obtain that

Thus we have the following theorem from (2.1) and (2.6).

Theorem 2.1.

Thus, we have

For , let us define the -adic functional as follows:

From (2.3) and (2.12), we have the following result.

Theorem 2.2.

By (2.9), (2.10), and (2.11), we see that

Now let us define the -adic functional as follows:

Then it follows from (2.14) that

By (2.15) and (2.16), we obtain that

On the other hand, the symmetric property of shows that

Comparing the coefficients on the both sides of (2.18) and (2.19), we have the following theorem.

Theorem 2.3.

From the symmetric property of , we also see that

Comparing the coefficients on the both sides of (2.22) and (2.23), we obtain the following theorem.

Theorem 2.5.
