摘要
对二级食物链反应扩散模型建立了一个线性化的二层差分格式,利用离散的内插不等式及能量估计方法证明了差分格式解的存在唯一性、收敛性、稳定性,并证明了其在无穷范数意义下的收敛阶为O(τ2+h2).
A two-level finite difference scheme was established for secondary reaction-diffusion model. The existence uniqueness, convergence and stability of the difference solution were proved. The convergence order was O(r^2 + h^2 ) under L∞ norm.
