On Weighted Norm Inequalities for Positive Linear Operators
Let T be a positive linear operator defined for nonnegative functions on a rj-finite measure space {X,m,fi). Given 1 < p < oo and a nonnegative weight function w on X , it is shown that there exists a nonnegative weight function v , finite /¿-almost everywhere on X , such that (1) I \Tf)*wdfi< j fvd/i, for all/>0, J x J x tere exists posi ( h if and only if th tive /¿-almost everywhere on X...
متن کاملYoung Type Inequalities for Positive Operators
In this paper we present refinements and improvement of the Young inequality in the context of linear bounded operators.
متن کاملOn some fuzzy positive and linear operators
The purpose of this work is to show that fuzzy Bernstein-Stancu operators introduced in [3] satisfy an A-statistical version of fuzzy Korovkin theorem. Some properties of these operators are also proved. An example of new fuzzy positive and linear operators is presented.
متن کاملSingular value inequalities for positive semidefinite matrices
In this note, we obtain some singular values inequalities for positive semidefinite matrices by using block matrix technique. Our results are similar to some inequalities shown by Bhatia and Kittaneh in [Linear Algebra Appl. 308 (2000) 203-211] and [Linear Algebra Appl. 428 (2008) 2177-2191].
متن کاملThe Direct and Converse Inequalities for Jackson-Type Operators on Spherical Cap
Approximation on the spherical cap is different from that on the sphere which requires us to construct new operators. This paper discusses the approximation on the spherical cap. That is, the so-called Jackson-type operator {Jm k,s }∞ k 1 is constructed to approximate the function defined on the spherical cap D x0, γ . We thus establish the direct and inverse inequalities and obtain saturation ...
