【Abstract】 In this paper, Cohen-Grossberg neural networks model with reaction-diffusion terms of the form is investigated. By making use of the theory of topology degree and introducing a new type of Lyapunov functional , some sufficient conditions for existence of equilibrum and global exponential stability of the Cohen-Grossberg neural networks are obtained.更多还原
