講　題：Traveling Wave Solutions of Delayed Lattie Differential System in Lotka-Volterra Type

摘　要：

In this work we consider the existence of traveling plane wave solutions of a class of delayed lattice differential system in Lotka-Volterra type. Employing the techniques of cross iteration method coupled with the explicit construction of upper and lower solutions in the theory of weak quasi-monotone dynamical systems, we obtain a critical speed, and show the existence of traveling plane wave solutions connecting two different equilibria when the wave speeds are less than the critical speed.
