摘要
基于现实的考虑,研究了具有阶段结构的竞争模型,用上、下解方法证明了具有时滞的两个物种竞争的微分方程的行波解的存在性.
Based on the realistic consideration, there are many species have competitive ability only when they becom adults, so we need study such problems by dividing them into stage structures.In this paper,we will prove the existence of a traveling front solution of delay differential equations for the interaction between two species, the adult members of which are in competition.
