#### Abstract

We give some new identities on the Bernoulli and Euler numbers by using the bosonic *p*-adic integral on and reflection symmetric properties of Bernoulli and Euler polynomials.

#### 1. Introduction

Let be a fixed prime number. Throughout this paper , and will denote the ring of -adic rational integers, the field of -adic rational numbers, and the completion of algebraic closure of . Let be the space of uniformly differentiable functions on . For , the bosonic -adic integral on is defined by From (1.1), we note that see [1]. As is well known, the ordinary Bernoulli polynomials are defined by the generating function as follows: see [1–19], where we use the technical notation by replacing by , symbolically. In the special case, , are called the -th ordinary Bernoulli numbers. That is, the generating function of ordinary Bernoulli numbers is given by see [1–19]. From (1.4), we can derive the following relation: see [1, 10], where is the Kronecker symbol.

By (1.3) and (1.4), we easily get By (1.2) and (1.3), we easily get see [1, 10]. From (1.7), we can derive Witt’s formula for the -th Bernoulli polynomials as follows: see [11]. By (1.1) and (1.8), we easily see that Thus, by (1.8) and (1.9), we get reflection symmetric relation for the Bernoulli polynomials as follows: The ordinary Euler polynomials are defined by the generating function as follows: with the usual convention about replacing by (see [8, 9]). In the special case, , are called the -th Euler numbers (see [8, 9]).

From (1.11), we note that By comparing the coefficients on both sides of (1.11) and (1.12), we obtain the following reflection symmetric relation for Euler polynomials as follows: The equations (1.10) and (1.13) are useful in deriving our main results in this paper.

For , the Bernstein polynomials are defined by see [13]. By (1.14), we easily get .

In this paper we consider the -adic integrals for the Bernoulli and Euler polynomials. From those -adic integrals, we derive some new identities on the Bernoulli and Euler numbers.

Let us consider the following -adic integral on for the product of Bernoulli and Euler polynomials as follows: On the other hand, by (1.10) and (1.13), one gets Equating (2.16) and (2.17), one gets For , by (2.18), one gets Therefore, by (2.19), one obtains the following theorem.
