Upper Semicontinuity of Pullback Attractors for the 3D Nonautonomous Benjamin-Bona-Mahony Equations [PDF]

open access: yesThe Scientific World Journal, 2014
We will study the upper semicontinuity of pullback attractors for the 3D nonautonomouss Benjamin-Bona-Mahony equations with external force perturbation terms. Under some regular assumptions, we can prove the pullback attractors 𝒜ε(t) of equation ut-Δut-

Upper semicontinuity of attractors for nonclassical diffusion equations with arbitrary polynomial growth

open access: yesAdvances in Difference Equations, 2021
In this paper, we mainly investigate upper semicontinuity and regularity of attractors for nonclassical diffusion equations with perturbed parameters ν and the nonlinear term f satisfying the polynomial growth of arbitrary order p − 1 $p-1$ ( p ≥ 2 $p ...

Upper Semicontinuous Extensions of Binary Relations [PDF]

open access: yesSSRN Electronic Journal, 2002
The notion of consistency in binary relations is considered. The authors provide sufficient conditions for the existence of upper semicontinuous extensions of consistent rather than transitive relations. For asymmetric relations, consistency and upper semicontinuity suffice.

The stability of minimal solution sets for set optimization problems via improvement sets

open access: yesJournal of Inequalities and Applications, 2023
In this paper we investigate the stability of solution sets for set optimization problems via improvement sets. Some sufficient conditions for the upper semicontinuity, lower semicontinuity, and compactness of E-minimal solution mappings are given for ...

On upper semicontinuity of duality mappings [PDF]

open access: yesProceedings of the American Mathematical Society, 1994
We give new sufficient conditions for a Banach space to be an Asplund (or reflexive) space in terms of certain upper semicontinuity of the duality mapping.

Semicontinuity and closedness of parametric generalized lexicographic quasiequilibrium problems

open access: yesJournal of Inequalities and Applications, 2016
This paper is mainly concerned with the upper semicontinuity, closedness, and the lower semicontinuity of the set-valued solution mapping for a parametric lexicographic equilibrium problem where both two constraint maps and the objective bifunction ...

Subharmonicity without Upper Semicontinuity

open access: yesJournal of Functional Analysis, 1997
Let \(\Omega\subseteq \mathbb{R}^d\) be open and let \(x\in\Omega\). There are many probability measures \(\mu\) with compact support in \(\Omega\) which have the following property: \(u(x)\leq\int u d\mu\) for every subharmonic function \(u\) on \(\Omega\). (Such a measure is called a Jensen measure for \(x\).) Familiar examples are normalized surface

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.

Concerning Upper Semicontinuous Decompositions of Irreducible Continua [PDF]

open access: yesProceedings of the American Mathematical Society, 1971
Let K \mathcal {K} denote the class of all compact metric continua K such that there exists a monotone mapping from a compact metric irreducible continuum M onto an arc such that each point inverse is homeomorphic to K. It is shown that no connected 1-polyhedron other than an arc is an element of K

Characteristic cycles and Gevrey series solutions of $A$-hypergeometric systems [PDF]

open access: yes, 2019
We compute the $L$-characteristic cycle of an $A$-hypergeometric system and higher Euler-Koszul homology modules of the toric ring. We also prove upper semicontinuity results about the multiplicities in these cycles and apply our results to analyze the ...
