On a Modification of (p, q)-Szasz-Mirakyan Operators

Abstract

In the present paper, we construct and investigate a variant of modified (p, q)-Szasz-Mirakyan operators, studied in Acar (Math Methods Appl Sci 39(10):2685-2695, 2016), which reproduce the test function The order of approximation of the operators via Peetre -functional, weighted approximation properties and approximation for functions in a Lipschitz space are discussed.
