摘要

Very recently Gupta and Heping [V. Gupta, W. Heping, The rate of convergence of q-Durrmeyer operators for 0 < q < 1, Math Meth. Appl. Sci. 31 (16) (2008) 1946–1955] introduced certain q-Durrmeyer type operators and established some approximation properties. In the present paper, we study some direct results for the certain q-Durrmeyer type operators.
