摘要
讨论在两斑块生态环境下 ,具有有关文献中 Cosner型功能性反应的竞争捕食扩散系统 .在一定条件下实现了系统的一致持久性 .通过构造 V泛函 ,得到了正概周期解的存在唯一性、全局吸引性和在壳扰动下的稳定性 .
A competition and prey predator model with diffusion is considered By using the V funtional and the definition of almost periodic solution and the stability under the disturbance from the hull,the existence,uniqueness and their stability of periodic and almost periodic solutions are obtained
