摘要
通过定义上下解,在反应项是拟单调的条件下,利用Schauder不动点定理得到了具有时滞和超前反应扩散方程波前解的存在性.
Existence of traveling wave front for reaction diffusion systems with retardation and anticipation is obtained by defining the upper and lower solutions and using Schauder's fixed point theorem when the reaction term satisfies the quasi-monotonicity condition.
