Spreading speeds for Fisher-KPP equations with slowly decaying initial data in an almost periodic setting
Xing Liang, Linfeng Xu, Tao Zhou
This paper investigates the long-times behavior of the Fisher-KPP equation with slowly decaying initial data in an almost periodic medium. We mainly focus on two classes of initial…

Spreading speeds for nonlocal Fisher--KPP equations with time-dependent asymmetric kernels
Zhucheng Jin, Tao Zhou
This paper investigates spreading speeds for nonautonomous Fisher--KPP equations with nonlocal diffusion. The dispersal kernel depends on time and may be asymmetric in space. We as…

Generalized principal eigenvalues of elliptic operators and spreading speeds of Fisher-KPP equations in two-scale almost periodic media
Xing Liang, Linfeng Xu, Tao Zhou
This paper is concerned with the asymptotic behavior of the generalized principal eigenvalues of elliptic operators and spreading speeds of Fisher-KPP equations in two-scale almost…
