WebFisher-KPP front propagating at this speed is referred to as a pulled front. It turns out that (1.1), like the Fisher-KPP equation, is a linearly determinate system in the sense that the nonlinear spreading speeds can be computed from the linearized equation. Spread- WebAbstract. The Fisher-KPP equation is a model for population dynamics that has generated a huge amount of interest since its introduction in 1937. The speed with which a population …
