摘要 对一个捕食模型的反应扩散方程组建立了一个线性化的二层差分格式,证明了差分格式解存在的唯一性、收敛性、稳定性,并证明了在无穷范数意义下的收敛阶为O(τ2+h2)。 A two-level finite difference scheme is established for the predator-prey reaction-diffusion formula group. The existence, uniqueness and stability of the difference solution are proved, and the convergence order under norm is O(τ^2+h^2).
