The Stability of Traveling Wave Front Solutions of a Reaction-Diffusion System

We investigate the behavior of solutions of the problem $\frac{\partial x}{\partial t} = F(x, y) + \frac{D \partial^2x}{\partial \zeta^2},\quad \frac{\partial y}{\partial t} = G(x, y),$ $x(\zeta, 0) = \varphi (\zeta), \quad y(\zeta, 0) = \psi (\zeta),$ where t ≥ 0 and $-\infty < \zeta < \infty...

Abstract We investigate the behavior of solutions of the problem $\frac{\partial x}{\partial t} = F(x, y) + \frac{D \partial^2x}{\partial \zeta^2},\quad \frac{\partial y}{\partial t} = G(x, y),$ $x(\zeta, 0) = \varphi (\zeta), \quad y(\zeta, 0) = \psi (\zeta),$ where t ≥ 0 and $-\infty < \zeta < \infty$. Under appropriate assumptions on F and G this system is a model similar to the degenerate forms (i.e., recovery variables kept at equilibrium values) of the Hodgkin-Huxley nerve conduction equations and the Field-Noyes model of the Belousov-Zhabotinskii chemical reaction. We prove the existence and uniqueness of a traveling wave front solution. Secondly, we demonstrate the stability of the traveling wave solution for a general class of initial data.

We investigate the behavior of solutions of the problem\[\begin{gathered} \frac{{\partial x}} {{\partial t}} = F( x,y ) + \frac{{D\partial ^2x }} {{\partial \zeta ^2 }},\quad \frac{{\partial y}} {{\partial t}} = G( x,y ), \hfill \\ x( \zeta ,0 ) = \varphi ( \zeta ),\quad y( \zeta ,0 ) = \psi ( \zeta ) \hfill \\ \end{gathered} \], where $t\geqq 0$ and $ - \infty < \zeta < \infty $. Under appropriate assumptions on $F$ and $G$ this system is a model similar to the degenerate forms (i.e., recovery variables kept at equilibrium values) of the Hodgkin-Huxley nerve conduction equations and the Field-Noyes model of the Belousov-Zhabotinskii chemical reaction. We prove the existence and uniqueness of a traveling wave front solution. Secondly, we demonstrate the stability of the traveling wave solution for a general class of initial data.
