Differences of Positive Linear Operators on Simplices [PDF]

Journal of Function Spaces, 2021
The aim of the paper is twofold: we introduce new positive linear operators acting on continuous functions defined on a simplex and then estimate differences involving them and/or other known operators.

Approximation Strategy by Positive Linear Operators [PDF]

Journal of Function Spaces and Applications, 2013
Summary: Two important techniques to achieve the Jackson type estimation by Kantorovich type positive linear operators in \(L^p\) spaces are introduced in the present paper, and three typical applications are given.

Approximation of functions of two variables by certain linear positive operators

, 2007
We introduce certain linear positive operators and study some approximation properties of these operators in the space of functions, continuous on a compact set, of two variables.

Approximation by Certain Linear Positive Operators of Two Variables

Abstract and Applied Analysis, 2014
We introduce positive linear operators which are combined with the Chlodowsky and Szász type operators and study some approximation properties of these operators in the space of continuous functions of two variables on a compact set. The convergence rate

DETECTABILITY OF LINEAR DISCRETE TIME LINEAR SYSTEMS DEFINED BY POSITIVE OPERATORS [PDF]

Fiabilitate şi Durabilitate, 2010
In this paper we extend the notion of detectability, introduced in [1] in connection with stochastic systems, to a more general class of linear discrete time systems defined by positive operators.

On unitarily invariant norms of matrix-valued linear positive operators

Journal of Inequalities and Applications, 2002
In this paper we prove several inequalities concerning invariant norms of matrices belonging to the range of some matrix-valued Linear Positive Operator (LPO).

Generalized Kantorovich modifications of positive linear operators

Mathematical Foundations of Computing, 2023
Starting with a positive linear operator we apply the Kantorovich modification and a related modification. The resulting operators are investigated.

Approximation of functions with linear positive operators which fix {1, φ} and {1, φ2}

, 2020
In this manuscript, linear and positive operators described on bounded and unbounded intervals that fix the function sets {1, φ} and {1, φ2} such that φ ∈ C[0, 1] are presented. Then we present different types of operators by choosing different functions
