WebThe above equation (1.2) was first introduced separately by Fisher [22] and Kolmogorov, Petrovsky and Piskunov [28], when the nonlinear function F satisfies the Fisher-KPP conditions. Recall that a typical example of such Fisher-KPP nonlinearity is given by the logistic function F(u) = u(1− u). WebJun 1, 2024 · The Fisher–KPP equation is a reaction-diffusion system that can be used to model population growth and wave propagation. The proposed method is based on the operator splitting method and an ...
