报告摘要1:Taking into account the depletion of the food supply by all prey, and the fact that chronic infectious diseases will not cause the infected prey to lose their fertility completely, we propose an eco-epidemiological prey-predator model with infectious diseases in prey, including the ODE model and PDE models with the homogeneous Neumann and Dirichlet boundary conditions. For the ODE model and PDE model with the homogeneous Neumann boundary condition, we give a complete conclusion about the stabilities of nonnegative constant equilibrium solutions. For 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.
