Also, using -Bernstein polynomials with two variables, we derive some interesting properties associated with -Bernoulli numbers with weight (,).

1. Introduction

In many areas the Bernstein polynomials have many applications: in statistics, in computer applications, in approximations of functions, in numerical analysis, in -adic analysis, and in the solution of differential equations. In particular, recognition of human speech has long been a hot issue among artificial intelligence and signal processing researchers, and -Bernstein polynomials, which are mathematical operators, have been applied for pattern recognition, and a new method has thus been developed. For -Bernoulli numbers and polynomials, several results have been studied by Carlitz (see [1, 2]), Kim (see [37]), Ozden et al. (see [8]), and M.-S. Kim et al. (see [9]). Bernoulli numbers and polynomials possess many interesting properties and arise in many areas of mathematics, mathematical physics, and statistical physics. Recently, many mathematicians have studied in the area of Bernoulli numbers and polynomials. First, we introduce the -Bernoulli numbers and polynomials with weight as extended measure. And we investigate some identities due to the -Bernoulli numbers and polynomials with weight . Second, we consider the -adic analogue of the extended -Bernstein polynomials on and investigate some properties of several extended -Bernstein polynomials by using the bosonic -adic -integral. Finally, we investigate the relation of Bernstein polynomials and Bernoulli numbers and polynomials using -adic -integral on .

Throughout this paper, we use the following notations. By we denote the ring of -adic rational integers, denotes the field of -adic rational numbers, denotes the completion of algebraic closure of , denotes the set of natural numbers, denotes the ring of rational integers, denotes the field of rational numbers, denotes the set of complex numbers, and .
