具有时滞和时变系数的Cohen-Grossberg神经网络的收敛性
Convergence of Cohen-Grossberg Neural Networks with Delays and Time-varying Coefficients
【摘要】 利用数学分析方法,讨论了具有时滞时变系数的Cohen-Grossberg神经网络的收敛性,给出了确保网络的所有解指数收敛于零点的充分条件,补充了已有的结论.
【Abstract】 By using mathematical analysis technique,the convergence behavior of Cohen-Grossberg neural networks with delays and time-varying coefficients are considered.Some sufficient conditions are established to ensure that all solutions of the networks converge exponentially to zero point,which are new and complement of previously known results.
