研究了一类单稳态反应扩散系统行波解的稳定性,该系统描述了一类细菌和病毒在人类环境疾病中的空间传播。从数学上证明了该系统在任意允许波速(包括临界波速)下行波解的全局稳定性,并对某些反应函数,数值计算了在波尾附近给定初始函数的临界波速和Cauchy问题的解,分别证明了在非临界波速和临界波速下行波解的全局稳定性.
We study the stability of travelling wave solutions for a monostable reaction-diffusion system which describes the spatial spread of a class of bacterial and viral in man-environment diseases. Mathematically we prove the global stability of traveling wave solutions withanyadmissible wave speed (includingthe critical wave speed) for the system, and compute numerically the critical wave speed and solutions of the cauchy problem with given initial functions close to the travelling waves at the wave tail for some reaction functions to show the global stability of traveling wave solutions with noncritical wave speed and critical wave speed, respectively.
