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.

Sharp Hardy-Sobolev Inequalities with General Weights and Remainder Terms

open access: yesJournal 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 Stochastic Gronwall Lemma [PDF]

open access: yes, 2013
We prove a stochastic Gronwall lemma of the following type: if $Z$ is an adapted nonnegative continuous process which satisfies a linear integral inequality with an added continuous local martingale $M$ and a process $H$ on the right hand side, then for ...

RELATIVITY, INEQUALITY, AND OPTIMAL NONLINEAR INCOME TAXATION [PDF]

open access: yesInternational Economic Review, 2013
How does concern for consumption relative to others (“relativity”) affect the structure of optimal nonlinear income taxation? Our article provides three sets of answers to this general question. First, it supports the conclusion in the literature that relativity leads to higher marginal tax rates. In doing so, it both generalizes some of the conditions

Pain and Patient‐Reported Physical Function Did Not Differ Between Body Composition Profiles in Patients with Hip Osteoarthritis

open access: yesArthritis Care &Research, Accepted Article.
Objective To explore whether higher body fat and lower lean mass are associated with greater pain and worse patient‐reported physical function in individuals with hip osteoarthritis (OA). A secondary aim was to examine whether pain and patient‐reported physical function differ according to four body composition profiles: high body fat, low lean mass ...

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

open access: yesAbstract 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.

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.

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems

open access: yesInternational Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.
A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

Kawamata-Miyaoka-type inequality for $\mathbb Q$-Fano varieties with canonical singularities II: Terminal $\mathbb Q$-Fano threefolds [PDF]

open access: yesÉpijournal de Géométrie Algébrique
We prove an optimal Kawamata-Miyaoka-type inequality for terminal $\mathbb Q$-Fano threefolds with Fano index at least $3$. As an application, any terminal $\mathbb Q$-Fano threefold $X$ satisfies the following Kawamata-Miyaoka-type inequality \[ c_1(X ...

Optimal Concentration Inequalities for Dynamical Systems [PDF]

open access: yesCommunications in Mathematical Physics, 2012
For dynamical systems modeled by a Young tower with exponential tails, we prove an exponential concentration inequality for all separately Lipschitz observables of n variables. When tails are polynomial, we prove polynomial concentration inequalities. Those inequalities are optimal. We give some applications of such inequalities to specific systems and
