Periodic traveling wave solutions for a coupled map lattice

摘要: A type of coupled map lattice (CML) is considered in this paper. What we want to do define the form a traveling wave solution and reveal its existence. Due infinite property problem, have tried periodic case, which can be dealt with on finite set. The main approach for our study implicit existence theorem. results indicate that if parameters system satisfy some exact conditions, then there exists an neighborhood given one. However, these conditions are sufficient, but not necessary. In particular, 2-periodic solutions also obtained. It gives examples parameters, exist when satisfied.
