Logarithmic upper bounds and axial front selection for spatially periodic lattice Fisher--KPP equations

Yuanyang Hu, Zhenkun Wang

We study the position and shape of invasion fronts for spatially periodic Fisher--KPP equations on higher-dimensional lattices, starting from localized initial data. Periodic spect…

Bramson correction and convergence to the critical wave for Fisher-KPP equations on $Z^{d}$

Yuanyang Hu

We consider Fisher-KPP equations with nearest-neighbor diffusion on $Z^{d}$ , $d \geq 2$ , with nonzero finitely supported initial data. We prove a logarithmic delay of the front…

Sharp Propagation and the Local-to-Nonlocal Transition for Fractional Fisher-KPP Equations on Integer Lattices

Yuanyang Hu

Let $P$ denote normalized nearest-neighbor averaging on $Z^{d}$ and set $A = I - P$ . We consider $\partial_{t} u + A^{s} u = f (u), t > 0, x \in Z^{d}, 0 < s < 1.$ For a Fisher-KPP reaction…
