题目：Aneco-epidemiological prey-predator model with infectious diseases in prey

时间：10月23日下午4:30

地点：理工楼631

摘要：Eco-epidemiology has become a new interdisciplinary subject and is the frontier and hotspot of mathematical biology research so far. In this talk, we first formulate the basic eco-epidemiological model combining the SI epidemic model and the prey-predator model. Then study the ODE model, and diffusive model with the homogeneous Neumann and Dirichlet boundary conditions, respectively. For the ODE model and the diffusive model with the homogeneous Neumann boundary conditions, we give a complete conclusion about the stabilities of nonnegative equilibrium states (nonnegative constant equilibrium solutions). The results show that these two problems has no periodic solutions, and the diffusive model with the homogeneous Neumann boundary conditions has no yet Turing patterns. For the diffusive model with the homogeneous Dirichlet boundary conditions, we first establish the necessary and sufficient conditions for the existence of positive equilibrium solutions, and prove that the positive equilibrium solution is unique when it exists. Then we study the global asymptotic stabilities of trivial and semi-trivial nonnegative equilibrium solutions.
