Linear Operators in Banach Lattices and WeightedL2 Inequalities

Mathematische Nachrichten, 1987
This paper is a valuable confirmation of the general property: ``The boundedness properties of a linear operator in various Banach function spaces depend only on the weighted \(L^ 2\) inequalities that it satisfies.'' Let X be a 2-convex Banach function space on (\(\Omega,\mu)\) and \(\tilde X=(X^ 2)'\) is a Banach function space dual to \(X^ 2=\{y\in ...

Generalizations of Landau’s Inequality to Linear Operators

1972
In 1913 Edmund Landau [13] proved that if f is continuous together with its first and second order derivatives in the interval [0, 1], if ‖ f ‖ = 1, ‖ f″‖=4, then $$\left\| {f'} \right\| \mathbin{\lower.3ex\hbox ...

More operator inequalities for positive linear maps

2017
Summary: In this paper, we present some new operator inequality for convex functions. We have obtained a number of Jensen's type inequalities for convex and operator convex functions of self-adjoint operators for positive linear maps. Some results are exemplified for power and logarithmic functions.

Polya's inequality for positive linear operators

Rad Hrvatske akademije znanosti i umjetnosti. Matematičke znanosti, 1997
Recently, H.Alzer, generalizing an earlier result of G.Polya, gave an inequality involving the geometric mean of integrals. Here we give related results for means of bounded linear positive operators in Hilbert space.

A Problem Concerning an Inequality for Linear Operators

1983
Let X be an ordered topological vector space, and let A be a linear operator in X. Let us assume that the sequence Anx is convergent for every x ∈ X. Let K be the set of all solutions of the inequality $$Ax\,\leq\,x,\,x\,\varepsilon\,X$$ .
