On the -Euler Numbers and Polynomials with Weight
Abstract
The purpose of this paper is to investigate some properties of -Euler numbers and polynomials with weight 0. From those -Euler numbers with weight 0, we derive some identities on the -Euler numbers and polynomials with weight 0.
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 . The -adic absolute value is defined by where for with and . In this paper, we assume that and with . As well-known definition, the Euler polynomials are defined by with the usual convention about replacing by (see [1β15]).
In this special case, , are called the th Euler numbers (see [1]). Recently, the -Euler numbers with weight are defined by with the usual convention about replacing by (see [3, 12]). The -number of is defined by (see [1β15]). Note that . Let us define the notation of -Euler numbers with weight 0 as . The purpose of this paper is to investigate some interesting identities on the -Euler numbers with weight 0.

For , -adic Bernstein polynomial of degree is defined by (see [1, 6, 7]).
Let us take the fermionic -adic -integral on for one Bernstein polynomials in (2.31) as follows:
