题目：Propagation dynamics in a time-delayed nonlocal reaction-diffusion equation with a shifting environment

时间：6月27日（周六）下午4:20

地点：理工楼601

摘要：Thistalkinvestigates the spatial propagation dynamics of atime-delayed nonlocal equation in a shifting environment, which models the evolution of age-structured populations under climate change. The study demonstrates that the speed of environmental shift plays a pivotal role in spatial propagation. Specifically, we establish the existence of a critical threshold: when the environmental shifting speed exceeds this threshold, the equation admits a forced wave; conversely, when the shifting speed is below this threshold, no forced wave exists. Furthermore, we prove the uniqueness of the forced wave and its global stability in the sense that the forced wave attracts all other solutions originating from initial conditions with positive tail behavior.This is a joint work with Prof. Zhaoquan Xu.
