Resumen de Approximation via statistical K2a -convergence on two-dimensional weighted spaces

Sevda Yıldız

• We give a non-regular statistical summability method named statistical K2 a-convergence and prove a Korovkin type approximation theorem for this new and interesting convergence method on two-dimensional weighted spaces. We also study the rate of statistical K2 a-convergence by using the weighted modulus of continuity and afterwards we present a non-trivial application.
