Approximation properties of modified Szász-Mirakyan operators in polynomial weighted space

Abstract: We introduce certain modified Szász-Mirakyan operators in polynomial weighted spaces of functions of one variable. We studied approximation properties of these operators

On lupas-jain-beta operators

In this paper, an integral variant of the Lupas operators are investigated. The rate of convergence of these operators with the help of K-functional is discussed. Asymptotic formula, rate of convergence and weighted approximation results are established. At the end, we discussed better error estimation of these operators
