A Stable Finite-Difference Scheme for Population Growth and Diffusion on a Map.

A Stable Finite-Difference Scheme for Population Growth and Diffusion on a Map.

We describe a general Godunov-type splitting for numerical simulations of the Fisher-Kolmogorov-Petrovski-Piskunov growth and diffusion equation on a world map with Neumann boundary conditions. The procedure is semi-implicit, hence quite stable. Our principal application for this solver is modeling...
