Iterates of some bivariate approximation process via weakly Picard operators


In the present paper we introduce a general class of positive operators of discrete type acting on the space of real valued functions defined on a plane domain. Based on the weakly Picard operators and the contraction principle as well, our aim is to study the convergence of the iterates of our defined operators. Also, some approximation properties of this process are revealed and concrete examples of our approach are given.
