Operator inequalities associated with Hölder–McCarthy and Kantorovich inequalities
Journal of Inequalities and Applications, 1998 We discuss operator inequalities associated with Hölder–McCarthy and Kantorovich inequalities. We give a complementary inequality of Hölder–McCarthy one as an extension of [2] and also we give an application to the order preserving

Robust self-testing of quantum steering assemblages via operator inequalities
New Journal of PhysicsRobust self-testing provides a framework for certifying quantum resources under experimental imperfections. Improving robustness bounds for quantum resources such as quantum states, steering assemblages, and measurements is a constant effort that ensures

Generalized Hilfer Fractional Self Adjoint Operator Inequalities
, 2021 We give here ψ -Hilfer and Hilfer fractional self adjoint operator inner product comparison, Poincaré, Sobolev and Opial type inequalities. At first we give right and left ψ -Hilfer fractional representation formulae in the self adjoint operator sense ...

The Power of Unity: Collective Action and Smallholder Agricultural Performance in West Africa
Agribusiness, EarlyView.ABSTRACT We analyze the impact of collective action through farmer‐based organizations (FBOs) on smallholders' farm performance and income inequality in Ghana, Benin, The Gambia, and Mali. We find that FBO membership increases cereal yield in Ghana and The Gambia, legume yield in Mali, ruminant numbers in Benin and The Gambia, and total farm income in ...

Linear Algebra and its Applications, 2000 \textit{F. Hansen} [Proc. Am. Math. Soc. 125, No. 7, 2093-2102 (1997; Zbl 0870.47013)] gave a characterization of operator convex functions in terms of Jensen's operator inequality. Following investigations by \textit{S. Friedland} and \textit{M. Katz} [Linear Algebra Appl. 85, 185-190 (1987; Zbl 0612.15010)], the author presents a simple proof of this

Some Sharp L^2 Inequalities for Dirac Type Operators
Symmetry, Integrability and Geometry: Methods and Applications, 2007 We use the spectra of Dirac type operators on the sphere $S^n$ to produce sharp $L^2$ inequalities on the sphere. These operators include the Dirac operator on $S^n$, the conformal Laplacian and Paenitz operator.

The Inequalities for Quasiarithmetic Means
Abstract and Applied Analysis, 2012 Overview and refinements of the results are given for discrete, integral, functional and operator variants of inequalities for quasiarithmetic means. The general results are applied to further refinements of the power means.

Modular inequalities for the Calderón operator
Tohoku Mathematical Journal, 2000 The authors study increasing functions \(P,Q: [0,\infty )\rightarrow [0,\infty )\). Let \(S\) be the Calderón operator defined on positive decreasing functions, then they prove modular inequalities \(\int P(Sf)\leq C\int Q(f)\). The results are used to obtain weak type interpolation theorems for modular spaces.

A Predictor-Corrector Methods for Mixed Inverse Variational Inequalities
, 2009 In this paper, a class of mixed inverse variational inequalities is introduced and studied. We prove the existence of the solution of the auxiliary problem for mixed inverse variational inequalities, suggest a predictor-corrector method for solving the ...
