#### Abstract

The purpose of this paper is to give some arithmatic identities for the Bernoulli and Euler numbers. These identities are derived from the several -adic integral equations on .

#### 1. Introduction

Let be a fixed odd 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 , respectively. The -adic norm is normalized so that . Let be the set of natural numbers and .

Let be the space of uniformly differentiable functions on . For , the bosonic -adic integral on is defined by and the fermionic -adic integral on is defined by Kim as follows (see [1–8]):

The Euler polynomials, , are defined by the generating function as follows (see [1–16]): In the special case, , is called the th Euler number.

By (1.3) and the definition of Euler numbers, we easily see that with the usual convention about replacing by (see [10]). Thus, by (1.3) and (1.4), we have where is the Kronecker symbol (see [9, 10, 17–19]).

From (1.2), we can also derive the following integral equation for the fermionic -adic integral on as follows: see [1, 2]. By (1.3) and (1.6), we get Thus, by (1.7), we have see [1–8, 13–16].

The Bernoulli polynomials, , are defined by the generating function as follows: see [18]. In the special case, , is called the th Bernoulli number. From (1.9) and the definition of Bernoulli numbers, we note that see [1–19], with the usual convention about replacing by . By (1.9) and (1.10), we easily see that see [13].

From (1.1), we can derive the following integral equation on : where and .

By (1.12), we have Thus, by (1.13), we can derive the following Witt’s formula for the Bernoulli polynomials:

In [19], it is known that for , where if or .

The purpose of this paper is to give some arithmetic identities involving Bernoulli and Euler numbers. To derive our identities, we use the properties of -adic integral equations on .

Let us take the bosonic -adic integral on in (1.15) as follows: On the other hand, we get By (2.1) and (2.2), we get

Therefore, by (2.3), we obtain the following theorem.

Theorem 2.1. *For , one has
*

Now we consider the fermionic -adic integral on in (1.15) as follows: On the other hand, we get By (2.5) and (2.6), we get Therefore, by (2.7), we obtain the following theorem.

Theorem 2.2. *For , one has
*

Replacing by in (1.15), we have the identity: Let us take the bosonic -adic integral on in (2.9) as follows:

On the other hand, we see that By (2.10) and (2.11), we get Therefore, by (2.12), we obtain the following theorem.

Theorem 2.3. *For , one has
*

We consider the fermionic -adic integral on in (2.9) as follows: On the other hand, we get By (2.14) and (2.15), we obtain the following theorem.

Theorem 2.4. *For , one has
