反应扩散系统的慢动力学

Slow dynamics in reaction-diffusion systems

Marta Strani

摘要:

我们考虑一个系统的反应扩散方程在一个有界区间的实数线,重点是亚稳态动力学,从而依赖于时间的解决方案的渐近指数长的时间间隔接近稳态的粘度系数$\varepsilon>0$趋于零。为了严格描述这种行为,我们分析了远离系统稳定配置的分层解决方案的动态,我们推导出内部接口的位置的常微分方程。

英文摘要:

We consider a system of reaction-diffusion equations in a bounded interval of the real line, with emphasis on the metastable dynamics, whereby the time-dependent solution approaches the steady state in an asymptotically exponentially long time interval as the viscosity coefficient $\varepsilon>0$ goes to zero. To rigorous describe such behavior, we analyze the dynamics of layered solutions localized far from the stable configurations of the system, and we derive an ODE for the position of the internal interfaces.
