Asymptotic Behavior of the Kirchhoff Type Stochastic Plate Equation on Unbounded Domains

open access: yesComplexity, 2022
In this paper, we study the asymptotic behavior of solutions to the Kirchhoff type stochastic plate equation driven by additive noise defined on unbounded domains.

Upper semicontinuity of automorphism groups

open access: yesMathematische Annalen, 1994
The authors prove striking results on upper semicontinuity of automorphism groups. They show, for example, that if pairs \((M_j, G_j)\) \((M_j\) connected complex manifolds and \(G_j\) subgroups of \(\Aut (M_j))\) converge on compacta to a pair \((M,G)\), where \(M\) is a hyperbolic complex manifold and \(G\) is a subgroup of \(\Aut (M)\), then \(G_j\)

Dynamics of plate equations with time delay driven by additive noise in R n $\mathbb{R}^{n}$

open access: yesJournal of Inequalities and Applications, 2023
This paper is concerned with the asymptotic behavior of solutions for plate equations with delay blurred by additive noise in R n $\mathbb{R}^{n}$ . First, we obtain the uniform compactness of pullback random attractors of the problem, then derive the ...

The existence and the stability of solutions for equilibrium problems with lower and upper bounds [PDF]

open access: yes, 2012
In this paper, we study a class of equilibrium problems with lower and upper bounds. We obtain some existence results of solutions for equilibrium problems with lower and upper bounds by employing some classical fixed-point theorems.

Normal Hyperbolicity and Continuity of Global Attractors for a Nonlocal Evolution Equations

open access: yesInternational Journal of Differential Equations, 2014
We show the normal hyperbolicity property for the equilibria of the evolution equation ∂m(r,t)/∂t=-m(r,t)+g(βJ*m(r,t)+βh),  h,β≥0, and using the normal hyperbolicity property we prove the continuity (upper semicontinuity and lower semicontinuity) of the ...

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 ...

On the upper semicontinuity of Choquet capacities

open access: yesInternational Journal of Approximate Reasoning, 2010
AbstractThe Choquet capacity T of a random closed set X on a metric space E is regarded as or related to a non-additive measure, an upper probability, a belief function, and in particular a counterpart of the distribution functions of ordinary random vectors.

On separation axioms of uniform bundles and sheaves

open access: yesApplied General Topology, 2004
In the context of the theory of uniform bundles in the sense of J. Dauns and K. H. Hofmann, the topology of the fiber space of a uniform bundle depends on the assumption of upper semicontinuity of its defining set of pseudometrics when composed with ...

On the Wu metric in unbounded domains

open access: yes, 2007
We discuss the properties of the Wu pseudometric and present counterexamples for its upper semicontinuity that answers the question posed by Jarnicki and Pflug.
