英文摘要: This project is located in the applied basic research. The research target of this project is to reveal the mechanism of Hopf bifurcation of Hopfield impulsive delayed neural networks and Cohen-Grossberg impulsive delayed neural networks , explore effective method of Hopf bifurcation, and promote the development of theory and application of neural network and other related areas. The research contents include exploring the conditions of the existence of Hopf bifurcation for the two typical nonlinear impulsive delayed neural networks, analyzing the impacts of delay and impulsive term on the dynamics of neural networks, and verifying the correctness of the theory through numerical simulation.
