We establish some approximation properties in weighted spaces and we give a Voronovskaya type asymptotic formula for the composition of the Szäsz-Mirakyan and Durrmeyer-Chlodowsky operators.
Keywords and phrases:approximation, Szäsz-Mirakyan operators, Durrmeyer-Chlodowsky operators, modulus of continuity in weighted spaces, Voronovskaya type theorem.
