On Choquet theorem for random upper semicontinuous functions

International Journal of Approximate Reasoning, 2007
Let \((\Omega ,{\mathcal A},P)\) be a probability space, \(E\) a Hausdorff, locally compact and second countable topological space, and \(\mathcal U\) the family of all upper semicontinuous (u.s.c., for short) functions \(f:E\to [0,1]\). Using hypographs, \(\mathcal U\) can be embedded into the space \({\mathcal F}(E\times [0,1])\) of all closed ...

Semicontinuity of nullity or deficiency implies normability of the space [PDF]

, 1971
In this paper the upper semicontinuity of nullity and deficiency on locally convex spaces is examined. If either is semicontinuous in the topology of uniform convergence on bounded sets on L ( X ) L(X ...

Upper semicontinuity of uniform attractors for singular perturbed second order nonautonomous delay lattice systems

Electronic Journal of Differential Equations
In this article, we consider the upper semicontinuity of the uniform attractors for the singular perturbed second order nonautonomous delay lattice systems driven by the almost periodic forces as the coefficient of second order derivative term tends to ...

R-closedness and Upper semicontinuity

, 2012
Let $\mathcal{F} $ be a pointwise almost periodic decomposition of a compact metrizable space $X$. Then $\mathcal{F} $ is $R$-closed if and only if $\hat{\mathcal{F}} $ is usc. Moreover, if there is a finite index normal subgroup $H$ of an $R$-closed flow $G$ on a compact manifold such that the orbit closures of $H$ consist of codimension $k$ compact ...

Upper semicontinuity of the attractor for a nonlinear hyperbolic-parabolic coupled system with fractional Laplacian [PDF]

In this paper we establish the existence and uniqueness of global solutions (in time), as well as the existence, regularity and stability (upper semicontinuity) of the attractor for the semigroup generated by the solutions of a two-dimensional nonlinear ...

Pullback attractors for a class of non-Newtonian micropolar fluids

Electronic Journal of Differential Equations, 2018
In this article we study the long time behavior of the two-dimensional flow for non-Newtonian micropolar fluids in bounded smooth domains, in the sense of pullback attractors.

Limiting dynamics for stochastic complex Ginzburg-Landau systems with time-varying delays on unbounded thin domains

Demonstratio Mathematica
This study deals with the limiting dynamics for stochastic complex Ginzburg-Landau systems with time-varying delays and multiplicative noise on unbounded thin domains. We first prove the existence and uniqueness of pullback tempered random attractors for
