The present paper is a study of L p − approximation by a new type of Bernstein-Durrmeyer type operators. It turns out the order of approximation by these operators is at best O(n −1), however smooth the function may be. In order to speed up the rate of convergence by the operators P n , we apply the technique of iterative combinations given by Micchelli [9](More)
In this paper we obtain the estimates of the central moments for the recently defined q-analogue of Baskakaov-beta operators. We obtain the evaluation for the rate of convergence in term of the first modulus of smoothness and Voronovskaja-type theorem for these operators.
