Maximizers for the Stein-Tomas inequality [PDF]

open access: yes, 2016
We give a necessary and sufficient condition for the precompactness of all optimizing sequences for the Stein-Tomas inequality. In particular, if a well-known conjecture about the optimal constant in the Strichartz inequality is true, we obtain the ...

Optimal Szegö-Weinberger type inequalities

open access: yesCommunications on Pure and Applied Analysis, 2016
Denote with $ _{1}( ;e^{h\left(|x|\right)})$ the first nontrivial eigenvalue of the Neumann problem \begin{equation*} \left\{\begin{array}{lll} -\text{div}\left(e^{h\left(|x|\right)}\nabla u\right) = e^{h\left(|x|\right)}u & \text{in} & & & \frac{\partial u}{\partial }=0 & \text{on} & \partial , \end{array} \right. \end{

Optimal Inequalities for Power Means [PDF]

open access: yesJournal of Applied Mathematics, 2012
We present the best possible power mean bounds for the product for any p > 0, α ∈ (0,1), and all a, b > 0 with a ≠ b. Here, Mp(a, b) is the pth power mean of two positive numbers a and b.

Violation of Bell's inequality: criterion for quantum communication complexity advantage [PDF]

open access: yes, 2002
We prove that for every Bell's inequality and for a broad class of protocols, there always exists a multi-party communication complexity problem, for which the protocol assisted by states which violate the inequality is more efficient than any classical ...

Strichartz inequality for orthonormal functions [PDF]

open access: yes, 2013
We prove a Strichartz inequality for a system of orthonormal functions, with an optimal behavior of the constant in the limit of a large number of functions.

Analysis and control of a nonlinear boundary value problem

open access: yesNonlinear Analysis, 2017
We consider a nonlinear two-dimensional boundary value problem which models the frictional contact of a bar with a rigid obstacle. The weak formulation of the problem is in the form of an elliptic variational inequality of the second kind.

Set Optimization Meets Variational Inequalities [PDF]

open access: yes, 2015
We study necessary and sufficient conditions to attain solutions of set-optimization problems in therms of variational inequalities of Stampacchia and Minty type. The notion of a solution we deal with has been introduced Heyde and Loehne, for convex set-valued objective functions.

Optimal Control Problem for Non-linear Degenerate Parabolic Variation Inequality: Solvability and Attainability Issues

open access: yesJournal of Optimization, Differential Equations and Their Applications, 2023
We investigate the optimal control problem with respect to coefficients of the degenerate parabolic variational inequality. Since problems of this type can have the Lavrentieff effect, we consider the optimal control problem in a class of so-called ...

Fiscal policy, growth and income distribution in the UK [PDF]

open access: yes, 2015
Income and income inequality increased substantially in the UK during the industrial revolution. Income inequality was the highest around 1880. This triggered enactments of more egalitarian tax and transfer system, which halved income inequality by the ...

Optimal Inequalities for State-Independent Contextuality [PDF]

open access: yesPhysical Review Letters, 2012
Contextuality is a natural generalization of nonlocality which does not need composite systems or spacelike separation and offers a wider spectrum of interesting phenomena. Most notably, in quantum mechanics there exist scenarios where the contextual behavior is independent of the quantum state.
