摘要

In this paper, we consider a modification of Srivastava-Gupta operators, which is a general sequence of summation-integral operators. We are able to achieve faster convergence for our modified operators over the well known Srivastava-Gupta operators. Our results include some approximation properties, which include rate of convergence and Voronovskaya kind results. In the last section of this paper we give Stancu variant of these operators.
