Better Approximation of Functions by Genuine Baskakov Durrmeyer Operators
In this paper, we define a new genuine Baskakov-Durrmeyer operators. We give uniform convergence using the weighted modulus of continuity. Then we study direct approximation of the operators in terms of the moduli of smoothness. After that a Voronovskaya type result is studied.
