报告题目：Global threshold dynamics of a spatial chemotactic mosquito-borne disease model

报告人：王凯  广州大学

报告摘要：In this talk, I will introduce a mosquito-borne disease model with chemotaxis and spatial heterogeneity. We first prove the global existence and boundedness of solutions to guarantee the solvability of the model. Next, the threshold dynamics are obtained. Furthermore, we numerically explore the impacts of chemotactic effect, spatial heterogeneity and dispersal rates of infected individuals to provide a clear picture on disease severity. In particular, we find that the mosquito chemotaxis causes mild disease in some regions but severe in others, which suggests developing targeted strategies to control mosquitoes in specific locations and achieve a deep understanding on the chemotaxis.
