摘要
本文运用非奇异M矩阵的性质,不等式分析法和建立在重合度基础上的连续性定理,得到了带有周期系数和周期时滞的细胞神经网络的周期解的存在性以及全局指数稳定性的新判据。并且给出了指数收敛率的估计。
By using the properties of nonsingular M-matrix, inequity analysis and a continuation theorem based on the coincidence degree, derived in this paper are some new sufficient conditions ensuring existence and global exponential stability of periodic solution of cellular neural networks with periodic coefficients and delays, and at the same time, the exponentially convergent rates are also estimated.
