Instability of Stationary Solutions for Lotka-Volterra Competition Model with Diffusion

open access: yes, 1994
1991 Mathematics Subject Classification. 35B35.We consider the Lotka-Volterra competition model with diffusion on R, and study the stability of axial symmetric positive stationary solutions relative to the space X of bounded uniformly continuous ...

The ill-posedness of the (non-)periodic traveling wave solution for the deformed continuous Heisenberg spin equation

open access: yesOpen Mathematics
Based on an equivalent derivative non-linear Schrödinger equation, we derive some periodic and non-periodic two-parameter solutions of the deformed continuous Heisenberg spin (DCHS) equation.

Nonlinear Boundary Dynamics in Reaction-Diffusion-Advection Systems with Nonlocal Delay: Bifurcation and Stability

open access: yes
This paper develops a bifurcation and stability analysis for reaction-diffusion-advection systems incorporating three mathematically challenging features: directed movement along environmental gradients, nonlocal time-delayed competition, and nonlinear ...

On the weakly degenerate Allen-Cahn equation

open access: yesAdvances in Nonlinear Analysis, 2019
In this paper we consider a one-dimensional Allen-Cahn equation with degeneracy in the interior of the domain and Neumann boundary conditions. We allow the diffusivity coefficient vanish at some point of the space domain and we are addressed on the ...

Regularity of Solutions of Burgers' Equation with Globally Stabilizing Nonlinear Boundary Feedback

open access: yes, 2007
We consider the viscous Burgers equation under recently proposed nonlinear boundary conditions which guarantee global asymptotic stabilization and semiglobal exponential stabilization in H 1 sense.

One-Dimensional Transport Equations With Discontinuous Coefficients

open access: yes, 1998
We consider one-dimensional linear transport equations with bounded but possibly discontinuous coefficient a. The Cauchy problem is studied from two different points of view. In the first case we assume that a is piecewise continuous.

Boundedness and finite-time blow-up for the chemotaxis system with indirect signal production and flux limitation

open access: yesAdvances in Nonlinear Analysis
In this work, we consider a flux-limited chemotaxis model with indirect signal production and nonlinear diffusion,ut=∇⋅(D(u)∇u)−∇⋅(uf(|∇v|2)∇v)−k1u+k2w,x∈Ω,t>0,0=Δv−μ(t)+w,x∈Ω,t>0,wt=Δw−λ1w+λ2u,x∈Ω,t>0 $$\begin{cases}_{t}=\nabla \cdot \left(D\left(u ...
