摘要：Characterizing the spread of avian influenza within migratory birds has been a meaningful and interesting topic from both biological and mathematical respects. In this talk, we start with a simple ecological model of bird migration in two patches and approximate its dynamic threshold via a novel finite dimensional reduction method and asymptotic techniques. Next, we incorporate the ecological model with an epidemiological process and approximate the dynamic thresholds for the resulted epidemiological system. Finally, we discuss some possible extensions of our methods and results to the study of avian influenza spreading between migratory birds and domestic poultry. This is a joint work with Dr. Jianhong Wu (York University).
