Generalized Cahn‐Hilliard equations based on a microforce balance

open access: yesJournal of Applied Mathematics, Volume 2003, Issue 4, Page 165-185, 2003., 2003
We present some models of Cahn‐Hilliard equations based on a microforce balance proposed by M. Gurtin. We then study the existence and uniqueness of solutions.

Phragmén-Lindelöf alternative results and structural stability for Brinkman fluid in porous media in a semi-infinite cylinder

open access: yesOpen Mathematics, 2022
This article investigates the spatial behavior of the solutions of the Brinkman equations in a semi-infinite cylinder. We no longer require the solutions to satisfy any a priori assumptions at infinity.

Stability of constant steady states of a chemotaxis model [PDF]

open access: yesarXiv, 2021
The Cauchy problem for the parabolic--elliptic Keller--Segel system in the whole $n$-dimensional space is studied. For this model, every constant $A \in \mathbb{R}$ is a stationary solution. The main goal of this work is to show that $A < 1$ is a stable steady state while $A > 1$ is unstable.

Decay rates for solutions of a Timoshenko system with a memory condition at the boundary

open access: yesAbstract and Applied Analysis, Volume 7, Issue 10, Page 531-546, 2002., 2002
We consider a Timoshenko system with memory condition at the boundary and we study the asymptotic behavior of the corresponding solutions. We prove that the energy decay with the same rate of decay of the relaxation functions, that is, the energy decays exponentially when the relaxation functions decays exponentially and polynomially when the ...

Nonlinear elliptic–parabolic problem involving p-Dirichlet-to-Neumann operator with critical exponent

open access: yesAdvances in Nonlinear Analysis, 2023
We consider the nonlinear elliptic–parabolic boundary value problem involving the Dirichlet-to-Neumann operator of p-Laplace type at the critical Sobolev exponent.

Regularity and long time behavior of a doubly nonlinear parabolic problem and its discretization [PDF]

open access: yesarXiv, 2023
We study a doubly nonlinear parabolic problem arising in the modeling of gas transport in pipelines. Using convexity arguments and relative entropy estimates we show uniform bounds and exponential stability of discrete approximations obtained by a finite element method and implicit time stepping.

Attractors of multivalued semiflows generated by differential inclusions and their approximations

open access: yesAbstract and Applied Analysis, Volume 5, Issue 1, Page 33-46, 2000., 2000
We prove the existence of global compact attractors for differential inclusions and obtain some results concerning the continuity and upper semicontinuity of the attractors for approximating and perturbed inclusions. Applications are given to a model of regional economic growth.
