In this paper, we are concerned with the asymptotic behavior of solutions to the Cauchy problem (or initial-boundary value problem) of one-dimensional Keller-Segel model. For the Cauchy problem, we prove that the solutions time-asymptotically converge to the nonlinear diffusion wave whose profile is self-similar solution to the corresponding parabolic equation, which is derived by Darcy’s law, as in [11, 28]. For the initial-boundary value problem, we consider two cases: Dirichlet boundary… Expand


Convergence to nonlinear diffusion waves for solutions of the initial boundary problem to the hyperbolic conservation laws with damping
In this paper we consider a model of hyperbolic balance laws with damping on the quarter plane (x, t) e R+ x R+. By means of a suitable shift function, which will play a key role to overcome theExpand
Boundary Effect on Asymptotic Behaviour of Solutions to the p-System with Linear Damping
We consider the asymptotic behaviour of solutions to the p-system with linear damping on the half-line R+=(0, ∞),vt−ux=0,ut+p(v)x=−αu, with the Dirichlet boundary condition u|x=0=0 or the NeumannExpand
Aggregation vs. global diffusive behavior in the higher-dimensional Keller–Segel model
We consider the classical parabolic–parabolic Keller–Segel system {ut=Δu−∇⋅(u∇v),x∈Ω,t>0,vt=Δv−v+u,x∈Ω,t>0, under homogeneous Neumann boundary conditions in a smooth bounded domain Ω⊂Rn. It isExpand
Asymptotic Convergence of Solutions for One-Dimensional Keller-Segel Equations.
The second and third authors of this paper have constructed in [14] finite-dimensional attractors for the one-dimensional Keller-Segel equations. They have also remarked in [14, Section 7] that, whenExpand
Critical space for the parabolic-parabolic Keller–Segel model in Rd
Abstract We study the Keller–Segel system in R d when the chemoattractant concentration is described by a parabolic equation. We prove that the critical space, with some similarity to the ellipticExpand

Convergence to strong nonlinear diffusion waves for solutions to p-system with damping on quadrant

A blow-up mechanism for a chemotaxis model
We consider the following nonlinear system of parabolic equations: (1) ut =Δu−χ∇(u∇v), Γvt =Δv+u−av for x∈B R, t>0. Here Γ,χ and a are positive constants and BR is a ball of radius R>0 in R2. At theExpand
