Simultaneous approximation by a class of linear positive operators. (English) Zbl 1224.41071

Summary: Some direct theorems for the linear combinations of a new class of positive linear operators have been obtained for both pointwise and uniform simultaneous approximations. A number of well known positive linear operators such as gamma-operators of Muller, Post-Widder and modified Post-Widder operators are special cases of this class of operators.
