Threshold convergence results for a nonlocal time-delayed diffusion equation

黄锐华 南师范大学

摘要：This talk is about the asymptotic behavior for nonlocal dispersion Nicholson blowflies equation. We obtain the threshold results with optimal convergence rates for the original solution to the constant equilibrium. This is a joint work with Prof. M. Mei and Dr. Z. Wang.

Bistable pulsating wave of a competition model in rapidly varying media and its homogenization limit

余虓华 南师范大学

    摘要：In this talk, we will discuss the existence of bistable pulsating wave for a two-species competition system in rapidly periodically varying media and its homogenization limit as the spatial period tends to zero. Assuming that the homogenized system admits a bistable traveling wave, we first show the existence of pulsating wave for all small periods and determine the homogenization limit of the wave speed. Furthermore, in the case where the homogeneous wave is not stationary, we investigate the effects of spatial heterogeneity on the wave speeds. This is based on a joint work with Drs. Weiwei Ding and Rui Huang.
