Existence of Traveling Fronts for General Reaction Systems with Nonlinear Di?usion
具非线性扩散一般反应系统的行波解存在性

In this paper, the authors use the perturbation method to investigate the existence of traveling fronts for a general reaction system with nonlinear di?usion. Su?cient conditions for the existence of traveling wavefronts are obtained, which make the results in the related references derived easily. As an application the authors employ the obtained results to show the existence of traveling fronts for a specific reaction-di?usion system.
