报告摘要:Heterogeneous shifting environment has a solid background from climate change, pathogen spread in host, genetic shift and multi-stage invasion. In this talk, I will report some recent results on the forced waves and spreading properties (i.e, finite speed and accelerating propagation) for the KPP equations and reducible cooperation systems with nonlocal dispersal in shifting environments. In particular, we find a new propagation phenomenon which says that in the shifting environments, the solutions of such nonlocal equations with exponentially unbounded kernels spread to the left and right at different propagation speeds (maybe linear or accelerated).
