报告内容简介：

In this talk, a degenerate and time delayed virus infection model with spatial heterogeneity and general incidence is investigated. The well-posedness of the system, including global existence, uniqueness and ultimately boundedness of the solutions, as well as the existence of a global attractor, is discussed. The basic reproduction number   is defined and a characterization of   is presented. Without the compactness of the solution semiflow, we establish the global dynamics of the system based on  . In addition, when the system is spatially homogeneous, the unique infection steady state is globally asymptotically stable. Simulations are presented to illustrate our theoretical results.
