TY - JOUR TI - Approximation theorems for Szász-Mirakjan-Durrmeyer type operators AU - Herzog, Monika TI - Approximation theorems for Szász-Mirakjan-Durrmeyer type operators AB - In this paper we study an integral modification of Szász-Mirakjan type operators. The modification will be called Szász-Mirakjan-Durrmeyer type operators as in many papers examining this type of operators. We give direct approximation theorems for these operators using the modulus of continuity and the modulus of smoothness for functions belonging to exponential weighted spaces.
