Harnack-type inequalities and traveling waves for non-cooperative nonlocal diffusion systems
Bo-Sheng Chen, Chang-Hong Wu
In this paper, we establish a system-wide -norm Harnack-type inequality for positive solutions of weakly coupled nonlocal diffusion systems on , without assumin…

Invasion Fronts in Shifting Habitats and Competition Systems: A Hamilton-Jacobi Approach and Nonlocal Effects
King-Yeung Lam, Chang-Hong Wu, Xiao Yu
We review recent developments in the study of spreading phenomena in reaction--diffusion equations arising from ecological invasion models. Motivated by the conjecture of Shigesada…

On the logarithmic correction of transition fronts in shifting environments
King-Yeung Lam, Chang-Hong Wu
In this paper, we investigate the location of the spreading front and convergence to traveling wave profile of solutions to the Fisher-KPP equation in the following two cases: (i)…
