Generalized Bernstein-Kantorovich-type operators on a triangle

In this note, we construct generalized Bernstein-Kantorovich-type operators on a triangle. The concern of this note is to present a Voronovskaja-type and Gruss Voronovskaja-type asymptotic theorems, and some estimates of the rate of approximation with the help of K-functional, first and second order modulus of continuity. We also obtain Korovkin- and Voronovskaja-type statistical approximation theorems via weighted mean matrix method. Lastly, we show that the numerical results which explain the validity of the theoretical results and the effectiveness of the constructed operators.
