    Nonlinear Instability for a Leslie-Gower Predator-Prey Model with Cross Diffusion by Lina Zhang, Shengmao Fu

    Published 2013-01-01
    “…A rigorous mathematical characterization for early-stage spatial and temporal patterns formation in a Leslie-Gower predator-prey model with cross diffusion is investigated. Given any general perturbation near an unstable constant equilibrium, we prove that its nonlinear evolution is dominated by the corresponding linear dynamics along a fixed finite number of the fastest growing modes.…”
