报告摘要：

In this talk, I will present our current research results ontraveling waves for time-delayed reaction-diffusion equations with degeneracy.Different from the existing studies where there exists a minimum wave speed forthe traveling waves in the case of mono-stable type equations like Fisher-KPP,we recognize that, for the local reaction-diffusion equations with degeneratediffusion and time-delay, there is no traveling wave with minimum speed,namely, the waves exist only for all speed c>0, but not for c<0 nor c=0.The global stability in L^1-weighted space is also proved.

This talk is based on our two recent papers joint with Rui Huang,Chunhua Ji, Jingxue Yin published in J. Nonlinear Sci. (2018), and joint withTianyuan Xu, Shanming Ji and Jingxue Yin in J. Diff. Eqn. (2018).
