Logarithmic Bramson correction for Fisher--KPP equations on homogeneous trees

Edagardo Álvarez, Marina Murillo-Arcila, Rodrigo Ponce +1

In this paper, we study the Fisher--KPP equation \[ \partial_t u = αΔ_{\TT_{q+1}}u+βu(1-u), \] on the homogeneous \((q+1)\)-regular tree \(\TT_{q+1}\), with \(q\geq2\), for nontriv…
