Abstract

Son yıllarda, q-Bernstein polinomları yaklaşım teorisinde önemli bir konu olarak ortaya çıkmıştır. Çok sayıda çalışma bu polinomun yakınsama kriterlerini incelemiş, bunların önemini ve kullanışlılığını vurgulamıştır. Literatürde sıklıkla göz ardı edilen bir nokta, bu polinomların çekirdeklerinin değişken parametreli binom dağılımının olasılıklarına bağlı olmasıdır. Bu özellikten yararlanarak, binom bağımlılığına ilişkin bu polinomun basitleştirilmiş bir formunu geliştirdik; bu, değişken parametreli bir binom değişkeni için momentlerinin hesaplanmasını kolaylaştırmıştır. Bu yaklaşım yalnızca hesaplama süreçlerini basitleştirmekle kalmaz, aynı zamanda bu polinomun yakınsama özelliklerine de ışık tutar. Bu indirgenmiş formu inceleyerek yakınsama için bir üst sınır belirlenir. Bulgular, q-Bernstein polinomunun yaklaşım teorisindeki çok yönlülüğünü ve gücünü vurgular ve polinomun matematiksel temelleri ve potansiyel uygulamaları hakkında daha derin bir anlayış sağlar.

On the Convergence Analysis of Bernstein Operators

Abstract

In recent years, many studies have been conducted to emphasize the convergence criteria of the q-Bernstein polynomial and their importance. A point often overlooked in the literature is that the kernels of these polynomials depend on the probabilities of the variable parameter binomial distribution. Taking advantage of this property, we develop a simplified form of this polynomial for the binomial variable with variable parameters. This approach not only simplifies the computational processes but also sheds light on the convergence properties of this polynomial. By examining this reduced form, an upper bound for convergence is determined. The findings highlight the versatility and power of the q-Bernstein polynomial in approximation theory and provide a deeper understanding of the mathematical foundations and potential applications of the polynomial.
