报告题目:Generalized Transition Waves for Time-Dependent Reaction-Diffusion Cooperative System
报告摘要:In this talk, we consider the existence and stability of generalized transition waves of time-dependent reaction-diffusion cooperative system. In this talk, using the principal Lyapunov exponent and principal Floquent bundle theory of linear cooperative systems, we prove the existence of generalized transition waves in any given direction with speed greater than the spreading speed by constructing appropriate subsolutions and supersolutions. When the initial value is uniformly bounded with respect to a weighted maximum norm, we further show that all solutions converge to the generalized transition wave solutions exponentially in time.
