  Article:   THE GENERALIZATION OF VORONOVSKAJA’S THEOREM FOR A CLASS OF BIVARIATE OPERATORS.

Authors:  OVIDIU T. POP.
 
       
         
  Abstract:  In this paper we generalize Voronovakaja’s theorem and we give an approximation property for a class of bivariate operators and then, through particular cases, we obtain statements verified by the bivariate operators of Bernstein, Schurer, Durrmeyer, Kantorovich, Stancu and Bleimann, Butzer and Hahn.
