Transformation of the second order modulus by positive linear operators
Abstract We obtain estimates for the transformation of the second order modulus of continuity by positive linear operators which satisfy certain conditions, which are common to a large class of approximation operators.
An Extension of the Szasz-Mirakjan Operators
The paper is devoted to defining a new class of linear and positive operators depending on a certain function ' These operators generalize
Inverse theorems for multidimensional Bernstein-Durrmeyer operators in L p
Abstract In this paper, we consider the multidimensional Bernstein-Durrmeyer operators in L p (1⩽ p K -functionals and the smoothness of the functions they approximate.
