Global Attractor for Partial Functional Differential Equations with State-Dependent Delay

open access: yesAbstract and Applied Analysis, 2013
This work aims to investigate the existence of global attractors for a class of partial functional differential equations with state-dependent delay. Using the classic theory about global attractors in infinite dimensional dynamical systems, we obtain ...

Global Attractor for a Chemotaxis Model with Reaction Term

open access: yesJournal of Applied Mathematics, 2013
A chemotaxis model with reproduction term in a bounded domain Ω⊂Rn is discussed in this paper, where n=2,3. First, the existence of a global-in-time solution is given, and then a global attractor for this model is obtained.

Existence and regularity of a global attractor for doubly nonlinear parabolic equations

open access: yesElectronic Journal of Differential Equations, 2002
In this paper we consider a doubly nonlinear parabolic partial differential equation $$ frac{partial eta (u)}{partial t}-Delta _{p}u+f(x,t,u)=0 quad hbox{in }Omega imesmathbb{R}^{+}, $$ with Dirichlet boundary condition and initial data given.

Global dynamics of a fourth-order parabolic equation describing crystal surface growth

open access: yesNonlinear Analysis, 2019
In this paper, we study the global dynamics for the solution semiflow of a fourth-order parabolic equation describing crystal surface growth. We show that the equation has a global attractor in H4per(Ω) when the initial value belongs to H1per(Ω).
