All geographical distances are optimal

Cybergeo, 2020
Triangular inequality is one of the four mathematical properties of distance. Its respect derives from the optimal nature of the measurement of distance.

Optimal Inequalities for State-Independent Contextuality [PDF]

Physical 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.

Extensions of the Heisenberg-Weyl inequality

International Journal of Mathematics and Mathematical Sciences, 1986
In this paper a number of generalizations of the classical Heisenberg-Weyl uncertainty inequality are given. We prove the n-dimensional Hirschman entropy inequality (Theorem 2.1) from the optimal form of the Hausdorff-Young theorem and deduce a higher ...

Hilfer fractional evolution hemivariational inequalities with nonlocal initial conditions and optimal controls

Nonlinear Analysis, 2019
In this paper, we mainly consider a control system governed by a Hilfer fractional evolution hemivariational inequality with a nonlocal initial condition.

Optimal Szegö-Weinberger type inequalities

Communications on Pure and Applied Analysis, 2016
Denote with $μ_{1}(Ω;e^{h\left(|x|\right)})$ 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) =μe^{h\left(|x|\right)}u & \text{in} & Ω& & \frac{\partial u}{\partial ν}=0 & \text{on} & \partial Ω, \end{array} \right.

Adaptive Observer for Coupled Wave PDE and Infinite ODE With Sampled Data and Unknown Input: Application to Brain Hemodynamics Estimation

International Journal of Adaptive Control and Signal Processing, EarlyView.
This article proposes a convergent adaptive observer for a damped wave PDE and an infinite‐dimensional ODE coupled in cascade using sampled‐in‐space ODE state measurements. The proposed observer estimates the distributed states of the PDE and ODE along with unknown PDE parameters and spatial input.

Sharp Hardy-Sobolev Inequalities with General Weights and Remainder Terms

Journal of Inequalities and Applications, 2009
We consider a class of sharp Hardy-Sobolev inequality, where the weights are functions of the distance from a surface. It is proved that the Hardy-Sobolev inequality can be successively improved by adding to the right-hand side a lower-order term with ...

A Simple Exact Penalty Function Method for Optimal Control Problem with Continuous Inequality Constraints

Abstract and Applied Analysis, 2014
We consider an optimal control problem subject to the terminal state equality constraint and continuous inequality constraints on the control and the state.
