On the upper semicontinuity of Choquet capacities [PDF]

open access: yesInternational Journal of Approximate Reasoning, 2010
The distribution of a random closed set \(X\) in a locally compact second countable Hausdorff space \(E\) is uniquely determined by its capacity functional \(T(K)=\mathbf{P}(X\cap K\neq\emptyset)\) for all \(K\) from the family \(\mathcal{K}\) of compact sets.

Subharmonicity without Upper Semicontinuity [PDF]

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

Metric characterizations of upper semicontinuity [PDF]

open access: yesJournal of Mathematical Analysis and Applications, 1979
AbstractWe characterize upper semicontinuity of multifunctions in terms of upper Hausdorff semicontinuity, measure of non compactness and active boundary. The results are applicable in optimization, theory of best approximation and in metrizability theory.

Upper semicontinuity of attractors of non-autonomous dynamical systems for small perturbations [PDF]

open access: yesElectronic Journal of Differential Equations, 2002
We study the problem of upper semicontinuity of compact global attractors of non-autonomous dynamical systems for small perturbations. For the general nonautonomous dynamical systems, we give the conditions of upper semicontinuity of attractors for small

Stieltjes Differential Inclusions with Periodic Boundary Conditions without Upper Semicontinuity [PDF]

open access: yesMathematics, 2021
We are studying first order differential inclusions with periodic boundary conditions where the Stieltjes derivative with respect to a left-continuous non-decreasing function replaces the classical derivative.

Weak upper semicontinuity of pullback attractors for nonautonomous reaction-diffusion equations [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2019
We consider nonautonomous reaction-diffusion equations with variable exponents and large diffusion and we prove continuity of the flow and weak upper semicontinuity of a family of pullback attractors when the exponents go to $2$ in $L^\infty(\Omega)$.

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

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 ...

Upper and weak-lower semicontinuity of pullback attractors to impulsive evolution processes

open access: yes, 2021
In this paper, following the work done in [11], we deal with the upper and weak-lower semicontinuity of pullback attractors for impulsive evolution processes.

Lower semicontinuity of attractors for non-autonomous dynamical systems [PDF]

open access: yes, 2009
This paper is concerned with the lower semicontinuity of attractors for semilinear non-autonomous differential equations in Banach spaces. We require the unperturbed attractor to be given as the union of unstable manifolds of time-dependent hyperbolic

Decomposition of Topologies Which Characterize the Upper and Lower Semicontinuous Limits of Functions

open access: yesAbstract and Applied Analysis, 2011
We present a decomposition of two topologies which characterize the upper and lower semicontinuity of the limit function to visualize their hidden and opposite roles with respect to the upper and lower semicontinuity and consequently the continuity of ...
