The problem about the Limit Cycle of the Feedback Neural Network

反馈神经网络中的极限环问题王保云，杨绿溪，何振亚（东南大学无线电工程系，南京２１００１８）反馈神经网络是一种高度复杂的动力学系统，非线性特性使得它具有丰富的动力学特性。在这方面已开展了很多工作，现已知道：Ｈｏｐｆｉｅｌｄ网络在对称连接下总是稳定的，即...

The limit cycle of the feedback neural network is studied.It is proved that under certainconditions the feedback network has no limit cycle in a region.Additionally,the conclusiun that thenetworks have no ellipsoidal positively invariant sets and elliptical limit cycles is arrived with the helpof a transformation.
