Convergence and difference estimates between Mastroianni and Gupta operators. (English) Zbl 1538.41049
Summary: Gupta operators are a modified form of Srivastava-Gupta operators and we are concerned about investigating the difference of operators and we estimate the difference of Mastroianni operators with Gupta operators in terms of modulus of continuity of first order. We also study the weighted approximation of functions and obtain the rate of convergence with the help of the moduli of continuity as well as Peetre’s \(K\)-functional of Gupta operators.
