Pointwise asymptotic convergence of solutions for a phase separation model

Abstract

A new technique, combining the global energy and entropy balance equations
with the local stability theory for dynamical systems, is used for proving
that every solution to a nonsmooth temperaturedriven phase separation model
with conserved energy converges pointwise in space to an equilibrium as time
tends to infinity. Three main features are observed: the limit
temperature is uniform in space, there exists a partition of the physical body
into at most three constant limit phases, and the phase separation process has
a hysteresislike character.

Renormalization group method: Application to NavierStokes equation

The aim of this article is to present a rather unusual and partly heuristic
application of the renormalization group (RG) theory to the NavierStokes equations
with space periodic boundary conditions.
We obtain in this way a new nonlinear
renormalized equation with a nonlinear term which is invariant under the Stokes
operator.
Its relation to the NavierStokes equations is investigated for nonresonant
domains.

Global existence results for nonlinear Schrödinger equations with quadratic potentials
Volume 13, Number 2, Pages: 385  398, 2005

We prove that no finite time blow up can occur for nonlinear Schrödinger
equations with quadratic potentials, provided that the potential has a
sufficiently strong repulsive component. This is not obvious in
general, since the energy associated to the linear equation is not
positive. The proof relies essentially on two arguments: global
in time Strichartz estimates, and a refined analysis of the linear
equation, which makes it possible to
control the nonlinear effects.

Our aim in this article is to construct exponential attractors for
singularly perturbed damped wave equations that are continuous with
respect to the perturbation parameter. The main difficulty comes from
the fact that the phase spaces for the perturbed and unperturbed
equations are not the same; indeed, the limit equation is a
(parabolic) reactiondiffusion equation. Therefore, previous
constructions obtained for parabolic systems cannot be applied
and have to be adapted. In particular, this necessitates a
study of the time boundary layer in order to estimate the difference
of solutions between the perturbed and unperturbed equations. We note
that the continuity is obtained without time shifts that have been used
in previous results.

On a limiting system in the LotkaVolterra competition with crossdiffusion

In this paper we investigate a limiting system that arises from
the study of steadystates of the LotkaVolterra competition model with
crossdiffusion. The main purpose here is to understand
all possible solutions to this limiting system, which consists of a nonlinear
elliptic equation and an integral constraint. As far as existence and
nonexistence in one dimensional domain are concerned, our knowledge of the
limiting system is nearly complete. We also consider the qualitative
behavior of solutions to this limiting system as the remaining diffusion
rate varies. Our basic approach is to convert the problem of solving the
limiting system to a problem of solving its "representation" in a
different parameter space. This is first done without the
integral constraint, and then we use the integral constraint to find the
"solution curve" in the new parameter space as the diffusion rate varies.
This turns out to be a powerful method as it gives fairly precise
information about the solutions.

Scaleinvariant extinction time estimates for some singular diffusion equations

We study three singular parabolic evolutions: the secondorder total variation flow, the
fourthorder total variation flow, and a fourthorder surface diffusion law. Each has the property
that the solution becomes identically zero in finite time. We prove scaleinvariant estimates for
the extinction time, using a simple argument which combines an energy estimate with a suitable
Sobolevtype inequality.

In this article we give first a survey on recent results on some TrudingerMoser type inequalities, and their importance in the study of nonlinear elliptic equations with nonlinearities which have critical growth in the sense of TrudingerMoser. Furthermore, recent results concerning systems of such equations will be discussed.

Attractors for noncompact nonautonomous systems via energy equations

An extension to the nonautonomous case of the energy equation method
for proving the existence of attractors for noncompact systems is presented.
A suitable generalization of the asymptotic compactness
property to the nonautonomous case, termed uniform asymptotic compactness, is
given, and
conditions on the energy equation associated with an abstract class of
equations that assure the
uniform asymptotic compactness are obtained. This general formulation is then
applied to a
nonautonomous NavierStokes system on an infinite channel past an obstacle,
with timedependent
forcing and boundary conditions, and to a nonautonomous, weakly damped, forced
Kortewegde Vries equation on the real line.

Nonlocal heat flows preserving the L^{2} energy

We shall study L^{2} energy conserved solutions to the heat equation.
We shall first establish the global existence, uniqueness and
regularity of solutions to such nonlocal heat flows. We then extend the
method to a family of singularly perturbed systems of nonlocal parabolic
equations. The main goal is to show that solutions to these perturbed
systems converges strongly to some suitable weaksolutions
of the limiting constrained nonlocal heat flows of maps into a singular
space. It is then possible to study further properties of such suitable
weak solutions and the corresponding free boundary problem, which will
be discussed in a forthcoming article.

This paper is concerned with the existence of large positive spiky
steady states for SKT competition systems with crossdiffusion.
Firstly by detailed integral and perturbation estimates, the
existence and detailed fastslow structure of a class of spiky
steady states are obtained for the corresponding shadow system,
which also verify and extend some existence results on spiky steady
states obtained in [10] by different method of proof. Further
by applying special perturbation method, we prove the existence of
large positive spiky steady states for the original competition
systems with large crossdiffusion rate.
