Abstract
In the present paper, we construct and investigate a variant of modified (p, q)-Szász–Mirakyan operators, studied in Acar (Math Methods Appl Sci 39(10):2685–2695, 2016), which reproduce the test function \(x^{2}.\) The order of approximation of the operators via Peetre \({\mathcal {K}}\)-functional, weighted approximation properties and approximation for functions in a Lipschitz space are discussed.
