摘要:

通过构造两个拟单调的上下控制方程并利用Schauder不动点定理, 给出并证明了一类交叉单稳型时滞格微分方程行波解的存在性. 结果表明, 即使对这类交叉单稳型的格微分方程, 行波解对所有时滞持久存在.

关键词: 行波解, 时滞格微分方程, Schauder不动点定理, 交叉单稳非线性项

Abstract:

The existence of traveling wave solutions of  non\|local delayed lattice differential equations was proved by constructing two associated auxiliary delayed lattice differential equations with quasimonotonicity and using the Schauder’s fixed point theorem. The result implies that the traveling wave solutions of the delayed lattice differential equations with crossingmonostability are persistent for all  values of the delay.

Key words: traveling waves solution, delayed lattice differential equations, Schauder’s fixed point theorem, crossingmonostable nonlinearity
