Approximation Theory, Ismail-May operators, Baskakov basis, asymptotic formula, simultaneous approximation, weighted Korovkin's theoremAbstract
In the present paper, we introduce a modification of Ismail-May operators having weights of Baskakov basis functions. We estimate weighted Korovkin's theorem and difference estimates between two operators and establish a Voronovskaja type asymptotic formula in simultaneous approximation.
