Approximation on bivariate parametric-extension of Baskakov-Durrmeyer-operators

The main purpose of this article is to study the bivariate approximation generalization for Baskakov-Durrmeyer-operators with aid non-negative parametric variants suppose 0 ? ?1,?2 1. We obtain order by use modulus continuity in terms well known Peetre?s K-functional, Voronovskaja type theorems and Lipschitz maximal functions. Further, we also discuss here properties operators B?gel-spaces mixed-modulus continuity.
