Statistical Korovkin-Type Theory For Matirx-Valued Functions Of Two Variables

In this work, we investigate an approximation problem for matrix valued positive linear operators of two variables. Also using the A-statistical convergence which is stronger than Pringsheim convergence of double sequences, we prove a Korovkin-type approximation theorem for matrix valued positive linear operators of two variables. We also compute the rates of A-statistical convergence of this operators.
