具有分布滞量的微分系统的周期解和全局吸引性

Periodic Solutions and Global Attractivity of a Class of Differential Systems with Distributed Delay

利用重合度理论中的延拓定理和Ｌｙａｐｕｎｏｖ泛函方法讨论一类具有分布沥量的微分系统 的周期解的存在性和全局吸引性，得到了便于应用的新结果．

Using continuation theorem in coincidence degree theory and Lyapunov func- tional, the existence and global attractivity of periodic solutions of a class of differential systems dswith distributed delay are discussed. Some effective results are obtained.
