Approximation of generalized nonlinear Urysohn operators using positive linear operators

Radu Paltanea, Maria Cristina Pacurar


There are presented two methods for approximation of generalized Urysohn type operators. The first of them is the natural generalization of the method considered first by Demkiv in \cite{demkiv2}. The convergence results are given in quantitative form, using certain moduli of continuity. In the final part there are given few exemplifications, for discrete and integral type operators and in particular for Bernstein and Durrmeyer operators.
