報(bào)告題目:Existence and exponential stability of traveling waves for delayed reaction-diffusion systems
報(bào)告摘要:The purpose of this work is to investigate the existence and exponential stability of traveling wave solutions for general delayed multi-component reaction-diffusion systems. Following the monotone iteration scheme via an explicit construction of a pair of upper and lower solutions, we first obtain the existence of monostable traveling wave solutions connecting two different equilibria. Then, applying the techniques of weighed energy method and comparison principle, we show that all solutions of the Cauchy problem for the considered systems converge exponentially to traveling wave solutions provided that the initial perturbations around the traveling wave fronts belong to a suitable weighted Sobolev space. This talk is based on a joint work with Cheng-Hsiung Hsu and Tsi-Sheng Yang,Nonlinearity 31 (2018) 838–863.
