摘　　要：We consider the linear combinations of Baskakov-Durrmeyer operators and give the characterization in terms of the classical modulous of smoothness for ∞-norm by the means of the pointwise simultanrous ap- proximation.An equivalence ralalion between the derivatives of these operators and smoothness or functions is also presented.We consider the linear combinations of Baskakov-Durrmeyer operators and give the characterization in terms of the classical modulous of smoothness for ∞-norm by the means of the pointwise simultanrous ap- proximation.An equivalence ralalion between the derivatives of these operators and smoothness or functions is also presented.
