Extinction and propagation phenomena for semilinear parabolic equations on metric trees

Analysis of PDEs 2025-05-19 v1

Abstract

We study the Cauchy-Neumann problem on a regular metric tree T for the semilinear heat equation with forcing term of KPP type. Propagation and extinction of solutions, as well as asymptotical speed of propagation are investigated.
