摘要
本文基于积分守恒性质,应用离散算子方法,给出了三维血吸虫病模型第一齐次边值问题的离散格式,同时证明了数值解的非负性和有界性,较好地体现了这一问题的实际背景,另外给出了最优L^2模误差估计。
In this paper, we propose the discrete schemes for the first homogeneous boundaryvalue problems of the schistosomiasis model based on the method of discrete operator. Weprove that the approximate solutions keep nonnegative and satisfy the maximum principle,which embodies the nature of this problem. Furthermore, we obtain the optimal L^2-modelerror estimate.
