Upper semicontinuous differential inclusions without convexity [PDF]

open access: yesProceedings of the American Mathematical Society, 1989
We prove existence of solutions to the Cauchy problem for the differential inclusion x ˙ ∈ A ( x ) \dot x \in A(x) , when A A is cyclically monotone and upper semi-continuous.

Super‐Nash Performance

open access: yesInternational Economic Review, EarlyView.
ABSTRACT In this paper, I introduce a novel benchmark in games, super‐Nash performance, and a solution concept, optimin, whereby players maximize their minimal payoff under unilateral profitable deviations by other players. Optimin achieves super‐Nash performance in that, for every Nash equilibrium, there exists an optimin where each player not only ...

Second order perturbation theory for embedded eigenvalues

open access: yes, 2010
We study second order perturbation theory for embedded eigenvalues of an abstract class of self-adjoint operators. Using an extension of the Mourre theory, under assumptions on the regularity of bound states with respect to a conjugate operator, we prove

Convexity and upper semicontinuity of fuzzy sets

open access: yesComputers & Mathematics with Applications, 2004
AbstractSince almost all practical problems are fuzzy and approximate, fuzzy decision making becomes one of the most important practical approaches. One off the important aspects for formulating and for solving fuzzy decision problems is the concept of convexity.

Debt Ceilings With Fiscal Intransparency and Imperfect Electoral Accountability

open access: yesInternational Economic Review, EarlyView.
ABSTRACT We study optimal debt ceilings in a political‐agency model with uncertainty about both policymaker type (benevolent or selfish) and economic state (good or bad). Elections generate disciplining and selection effects that differ across pooling, hybrid, and separating equilibria induced by different ceilings.

Wong-Zakai approximations and long term behavior of second order non-autonomous stochastic lattice dynamical systems with additive noise

open access: yesAIMS Mathematics, 2022

The porous medium equation: Large deviations and gradient flow with degenerate and unbounded diffusion

open access: yesCommunications on Pure and Applied Mathematics, Volume 78, Issue 9, Page 1609-1655, September 2025.
Abstract The problem of deriving a gradient flow structure for the porous medium equation which is thermodynamic, in that it arises from the large deviations of some microscopic particle system is studied. To this end, a rescaled zero‐range process with jump rate g(k)=kα,α>1$g(k)=k^\alpha, \alpha >1$ is considered, and its hydrodynamic limit and ...

Calculus and heat flow in metric measure spaces and applications to spaces with Ricci bounds from below [PDF]

open access: yes, 2012
This paper is devoted to a deeper understanding of the heat flow and to the refinement of calculus tools on metric measure spaces (X,d,m). Our main results are: - A general study of the relations between the Hopf-Lax semigroup and Hamilton-Jacobi ...

Upper Semicontinuity of Attractors for a Non-Newtonian Fluid under Small Random Perturbations

open access: yesAbstract and Applied Analysis, 2014
This paper investigates the limiting behavior of attractors for a two-dimensional incompressible non-Newtonian fluid under small random perturbations. Under certain conditions, the upper semicontinuity of the attractors for diminishing perturbations is ...

Uniqueness on average of large isoperimetric sets in noncompact manifolds with nonnegative Ricci curvature

open access: yesCommunications on Pure and Applied Mathematics, Volume 78, Issue 9, Page 1656-1702, September 2025.
Abstract Let (Mn,g)$(M^n,g)$ be a complete Riemannian manifold which is not isometric to Rn$\mathbb {R}^n$, has nonnegative Ricci curvature, Euclidean volume growth, and quadratic Riemann curvature decay. We prove that there exists a set G⊂(0,∞)$\mathcal {G}\subset (0,\infty)$ with density 1 at infinity such that for every V∈G$V\in \mathcal {G}$ there ...
