Periodic solutions for shunting inhibitory cellular neural networks of neutral type with time-varying delays in the leakage term on time scales

A class of shunting inhibitory cellular neural networks of neutral type with time-varying delays in the leakage term on time scales is proposed. based on the exponential dichotomy of linear dynamic equations on time scales,fixed point theorems,and calculus on time scales we obtain some sufficient conditions for the existence and global exponential stability of periodic solutions for that class of neural networks. the results of this paper are completely new and complementary to the previously known results even if the time scale =or.moreover,we present illustrative numerical examples to show the feasibility of our results. © 2014 yongkun li et al.
