【摘要】该文研究一类具有时滞非自治泛函动力方程,用锥中的一个不动点定理研究了这类方程的正周期解的存在性,并且得到了正周期解存在的充分条件。进一步用 -导数代替普通意义下的倒数,同样也得到了正周期解的存在性的充分条件。

【Abstract】This paper deals with a new existence theorem for periodic solutions to a class of non-autonomous impulsive functional dynamic equation with delays on time scale by employing a fixed point theorem in cones. Use a fixed point therorem to obtain a positive solution.To apply the derivative instead of the general derivative,we can obtain a positive solution.

【Key words】Impulsive functional dynamic equation; Time scale; Periodic solution.
