Approximation of some classes of functions by Landau type operators
Abstract This paper aims to highlight a class of integral linear and positive operators of Landau type which have affine functions as fixed points. We focus to reveal approximation properties…
Read More On Landau-type approximation operators
AbstractIn this paper, we define and study a general class of convolution operators based on Landau operators. A property of these new operators is that they reproduce the affine functions,…
Read More Approximation properties of a family of integral type operators
AbstractIn this paper we consider a general class of linear positive processes of integral type. These operators act on functions defined on unbounded interval. Among the particular cases included are…
