On the optimal control for variational inequalities [PDF]

open access: yesJournal of Optimization Theory and Applications, 1976
We prove an existence theorem for the optimal control of variational inequalities governed by a pseudomonotone operator: the cost is assumed to be quadratic. Then, we give an extension of the theorem to more general costs (assuming the operator to be monotone); we also give a result on a perturbation problem.

Optimal Inequalities in Probability Theory: A Convex Optimization Approach [PDF]

open access: yesSIAM Journal on Optimization, 2005
Summary: We propose a semidefinite optimization approach to the problem of deriving tight moment inequalities for \(P(X\in S)\), for a set \(S\) defined by polynomial inequalities and a random vector \(X\) defined on \(\Omega\subseteq{\mathcal R}^n\) that has a given collection of up to \(k\)th-order moments.

Optimizing Improved Hardy Inequalities

open access: yesJournal of Functional Analysis, 2002
Let \(N\geq 3\) and \(\Omega\) be a bounded domain in \({\mathbb R}^N\) such that \(0\in \Omega\). The goal of the authors is to study a general improved Hardy inequality: For all \(u\in H^1_0(\Omega)\), \[ \int_{\Omega} \left|\nabla u\right|^2\geq \left(\frac{N-2}2\right)^2\int_{\Omega} \frac{\left|u\right|^2}{\left|x\right|^2}dx+b\int_{\Omega} Vu^2dx

Optimal taxation under regional inequality [PDF]

open access: yesEuropean Economic Review, 2014
We study how regional productivity di¤erences and labor mobility shape optimal Mirrleesian tax-transfer schemes. When tax schedules are not al- lowed to differ across regions, productivity-enhancing inter-regional migra- tion exerts a downward pressure on optimal marginal tax rates.

Smooth and Flexible Dual Optimal Inequalities

open access: yesINFORMS Journal on Optimization, 2022
We address the problem of accelerating column generation (CG) for set-covering formulations via dual optimal inequalities (DOIs). We study two novel classes of DOIs, which are referred to as Flexible DOIs (F-DOIs) and Smooth-DOIs (S-DOIs), respectively (and jointly as SF-DOIs). F-DOIs provide rebates for covering items more than necessary.

An optimal Hardy–Morrey inequality [PDF]

open access: yesCalculus of Variations and Partial Differential Equations, 2011
In this work we improve the sharp Hardy inequality in the case $p>n$ by adding an optimal weighted Hoelder semi-norm. To achieve this we first obtain a local improvement. We also obtain a refinement of both the Sobolev inequality for $p>n$ and the Hardy inequality, the latter having the best constant.

Optimal Littlewood-Offord Inequalities in Groups [PDF]

open access: yesCombinatorica, 2019
We prove several Littlewood-Offord type inequalities for arbitrary groups. In groups having elements of finite order the worst case scenario is provided by the simple random walk on a certain cyclic subgroup. The inequalities we obtain are optimal if the underlying group contains an element of certain order.

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.

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 ...

A General Inequality for CR-Warped Products in Generalized Sasakian Space Form and Its Applications

open access: yesAdvances in Mathematical Physics, 2021
In the present paper, by considering the Gauss equation in place of the Codazzi equation, we derive new optimal inequality for the second fundamental form of CR-warped product submanifolds into a generalized Sasakian space form.
