Durrmeyer type modification of (p,q)-Szász Mirakjan operators and their quantitative estimates

In the present paper, we introduce Durrmeyer type modification of -Szász Mirakjan operators. We estimate the rate of convergence and local approximation behavior of the operators using modulus of continuity and Peetre’s -functional. We compute the quantitative estimates for difference of the proposed operators with -Szász Mirakjan operators and -Szász Mirakjan Kantorovich operators.
