Abstract
A generalization of Szàsz type operators
for two variables is constructed and the theorems on convergence
and the degree of convergence are established. In addition, we
consider the simultaneous approximation of these operators.
Keywords: Szàsz type operator; modulus of smoothness; $K$-functional; rate of convergence; divided difference.
