报告摘要：This talk is devoted to the dynamical behavior of solutions to some free boundary problems with time-delay and advection. We obtain that when the coefficient of advection is small, there exists a vanishing-spreading dichotomy result; when the coefficient of advection is medium-sized, there exists a vanishing-transition-virtual spreading trichotomy result; when the coefficient of advection is large, only vanishing happens. We also show that the profiles of (virtual) spreading solutions are uniquely determined by the corresponding semi-waves.
