英文摘要: This project is concerned with some delayed evolution equations or stochastic delayed evolution equations, which come from physical, chemical, electronic, biological, epidemiological, neural network and so on. We study the existence , uniqueness and stability of traveling wave solutions, the impact of noise on the traveling wave solutions, the existence of entire solutions and the stability of planar waves. The main work is as followings: (1) the existence, uniqueness and stability of transition fronts to non-homogeneous delayed evolution equations; (2) the stability of traveling wave solutions of non-monotonic delayed evolution equations; (3) the impact of noise on the traveling wave solutions to delayed evolution equations; (4) the existence of entire solutions and stability of non-planar waves to delayed evolution equations.
