Spreading speeds of a nonmonotonic delayed equation in a shifting environment
APPLIED MATHEMATICS LETTERS(2024)
摘要
This article studies the spreading speeds of a nonlocal delayed reaction-diffusion equation in a shifting environment. The equation does not satisfy the quasimonotone property. Some auxiliary equations are given to estimate its spreading speeds. Applying the theory to an SIR model, we may observe different propagation terraces.
