 Bu
çalışmada düzgün dört yüzlü olmayan bir bölge üzerinde üç boyutlu Bernstein-Chlodowsky
polinomlarını ve bu operatörün q-analoğunu tanıtacağız. Bu lineer pozitif
operatörlerin yaklaşım özellikleri ve genelleştirmeleri yapılacaktır.
Operatörün yakınsaklık hızı süreklilik modülü anlamında hesaplanacaktır.

Approximation By Three-Dimensional q-Bernstein-Chlodowsky Polynomials

Öz

In the present paper we introduce positive linear three-dimensional
Bernstein-Chlodowsky polynomials on a non-tetrahedron domain and we get their
q-analogue. We obtain aproximation properties for these positive linear operators
and their generalizations in this work. The rate of convergence of this operators
is calculated by means of the modulus of continuity.
