## Abstract

## 1. Introduction

Let be a fixed odd prime. Throughout this paper , , and will, respectively, denote the ring of -adic rational integers, the field of -adic rational numbers, the rational number field, the complex number field, and the completion of algebraic closure of . For a fixed positive integer with , let

where lies in (cf. [124]).

Let be the set of natural numbers. In this paper we assume that with , which implies that for . We also use the notations

We say that is a uniformly differentiable function at a point and denote this property by , if the difference quotients have a limit as (cf. [124]).

For , the above distribution yields the bosonic -adic invariant -integral as follows:

From (1.5) we note that

We also introduce the classical Hölder inequality for the Lebesgue integral in [25].

## 2. Hölder Type Inequality for Fermionic -Adic Invariant -Integrals

In order to investigate the Hölder type inequality for , we introduce the new concept of the inequality as follows.

Definition 2.1.

For , we define the inequality on (resp., ) as follows. For (resp., ), (resp., ) if and only if (resp., ).

Let with . By substituting and into , we obtain the following equation:
(2.1)
(2.2)
(2.3)

From (2.1), (2.2), and (2.3), we derive

(2.4)

We remark that the th Frobenius-Euler numbers and the th Frobenius-Euler polynomials attached to algebraic number may be defined by the exponential generating functions (see [16]):

(2.6)

Then, it is easy to see that

(2.7)

From (2.4) and (2.7), we have the following theorem.

Theorem 2.2.

Let with . If one takes and , then one has

We note that for with ,

(2.9)

By Theorem 2.2 and (2.7) and the definition of -adic norm, it is easy to see that

(2.10)

for all with . We note that lies in . Thus by Definition 2.1 and (2.10), we obtain the following Hölder type inequality theorem for fermionic -adic invariant -integrals.

Theorem 2.3.

Let with and . If one takes and , then one has
