#### Abstract

In this paper, we study Carlitz’s type -Daehee polynomials and investigate the symmetric identities for them by using the -adic -integral on under the symmetry group of degree .

#### 1. Introduction and Preliminaries

Let be a fixed prime number. Throughout this paper, , , and will denote the ring of -adic integers, the field of -adic rational numbers, and the completion of the algebraic closure of , respectively. The -adic norm is normalized as . If , we normally assume , so that for . The -extension of is defined as for and for .

As is well known, Carlitz’s -Bernoulli numbers are defined bywith the usual convention about replacing by (see [1, 2]). Let be the space of uniformly differentiable functions on . For , the -adic -integral on is defined by Kim to be(see ). From (2), we note thatwhere and . In particular, if we take , then we have(see ). Kim et al.  defined the -Daehee polynomials by the generating function to beWhen , are called the Daehee numbers with -parameter. By (4), we getIn , we recall that the Daehee polynomials are given by the generating function to beand the -Bernoulli polynomials are given by the generating function to beWhen , are called the Daehee numbers and , , are called the -Bernoulli numbers. Kim  proved that Carlitz’s -Bernoulli polynomials can be represented by the -adic -integral on :Kim-Kim-Jang  gave symmetric identities for degenerate Berstein and degenerate Euler polynomials and also many mathematical researchers studied symmetry identities of various polynomials (see [1, 1517]). In this paper, we consider Carlitz’s type -Daehee polynomials and investigate the symmetry identities for them by using the -adic -integral on under the symmetry group of degree .

Let be the symmetry group of degree . For positive integers , we consider the following integral equation for the -adic -integral on .From (16), we have

As this expression is an invariant under any permutation , we have the following theorem.

Theorem 2. For , the expressionsare the same for any .

We observe that

From (26) and Theorem 1, we note thatTherefore, by Theorem 2 and (20), we obtain the following theorem.

Theorem 3. For , the expressionsare the same for any .

We observe that

From (22), we note thatBy (24), we getwhere
