报告摘要:In this talk, we consider some kinds of differential equation models with state-dependent delay. One is the existence of a global unstable manifold connecting the positive equilibrium to a slowly oscillating periodic orbit for a Nicholson's blowflies equation with state-dependent delay under a set of mild conditions on the parameters and the delay function. Another is the existence of periodic solutions of second-order differential equations with state-dependent delay by using perturbation methods and Browder's theorem on the existence of a nonejective fixed point. The last is the global dynamics of a cooperative model composed of two species with stage structure and state-dependent maturation delays. These works are jointly completed by Ling Zhang, Shangzhi Li, and me.
