摘要
In this paper, we are dealing with q analogue of Durrmeyer type modified the Baskakov operators with two parameter alpha and beta, which introduces a new sequence of positive linear q-integral operators. We show that this sequence is an approximation process in the polynomial weighted space of continuous function defined on the interval [0, a). We study moments, weighted approximation properties, the rate of convergence using a weighted modulus of smoothness, asymptotic formula and better error estimation for these operators.
