A limit model for thermoelectric equations

open access: yes, 2011
We analyze the asymptotic behavior corresponding to the arbitrary high conductivity of the heat in the thermoelectric devices. This work deals with a steady-state multidimensional thermistor problem, considering the Joule effect and both spatial and ...

Asymptotic properties of asymptotically homogeneous diffusion processes on a compact manifold

open access: yesJournal of the Mathematical Society of Japan, 1985
Let \(\{\xi(t),P_{s,x}\}\) be a time inhomogeneous diffusion with generator \(L_ t=2^{-1}a^{ij}(t,x)\partial^ 2/\partial x^ i\partial j^ j+b^ i(t,x)\partial/\partial x^ i\) and \(\{\lambda(t),P_ x\}\) be a homogeneous diffusion with generator \(L=2^{-1}a^{ij}(x)\partial^ 2/\partial x^ i\partial x^ j+b^ i(x)\partial /\partial x^ i\) such that for every ...

Stability of the essential spectrum for 2D--transport models with Maxwell boundary conditions

open access: yes, 2005
We discuss the spectral properties of collisional semigroups associated to various models from transport theory by exploiting the links between the so-called resolvent approach and the semigroup approach. Precisely, we show that the essential spectrum of

Pullback attractors for non-autonomous reaction–diffusion equation with infinite delays in Cγ,Lr(Ω) $C_{\gamma,L^{r}(\Omega)}$ or Cγ,W1,r(Ω) $C_{\gamma,W^{1,r}(\Omega)}$

open access: yesBoundary Value Problems, 2018
In this paper, the well-posedness for the non-autonomous reaction–diffusion equation with infinite delays on a bounded domain is established. The existence of pullback attractors for the process in Cγ,Lr(Ω) $C_{\gamma,L^{r}(\Omega)}$ and Cγ,W1,r(Ω) $C_ ...

Asymptotically Balanced Functions and Stochastic Compactness of Sample Extremes

open access: yesThe Annals of Probability, 1984
Let \(X_ n\) be the maximum of the first n terms of a sequence of independent random variables with common distribution function F. The sequence \(\{X_ n\}\) is called stochastically compact if there exist two sequences \(\{a_ n\}\) and \(\{b_ n\}\), \(a_ n>0\), such that every subsequence of \(\{(X_ n-b_ n)/a_ n\}\) contains a further subsequence ...

A remark on reaction-diffusion equations in unbounded domains

open access: yes, 2002
We prove the existence of a compact L^2-H^1 attractor for a reaction-diffusion equation in R^n. This improves a previous result of B. Wang concerning the existence of a compact L^2-L^2 attractor for the same equation.Comment: 6 pages; to appear on "Discr.

Coercivity Properties for Sequences of Lower Semicontinuous Functions on Metric Spaces

open access: yesAbstract and Applied Analysis, 2013
The paper presents various results studying the asymptotic behavior of a sequence of lower semicontinuous functions on a metric space. In particular, different coercivity properties are obtained extending and refining previous results.

Hybrid feedback for global asymptotic stabilization on a compact manifold [PDF]

open access: yes2017 IEEE 56th Annual Conference on Decision and Control (CDC), 2017
In this paper, we employ a hybrid feedback control strategy to globally asymptotically stabilize a setpoint on a smooth compact manifold without boundary satisfying the following: there exists a finite maximal atlas such that the desired setpoint belongs to each chart of the atlas.

Dynamics of stochastic nonclassical diffusion equations on unbounded domains

open access: yesElectronic Journal of Differential Equations, 2015
This article concerns the dynamics of stochastic nonclassical diffusion equation on $\mathbb{R}^N$ perturbed by a $\epsilon$-random term, where $\epsilon\in(0,1]$ is the intension of noise.
