摘要
本文研究年龄结构随机种群方程的离散误差,在空间离散中用到Galerkin公式,时间离散中用到显式欧拉公式.
In this paper,we investigate the discretization error of stochastic age-structured population equations in Baaach spaces, The spaces discretization may be done by Galerkin approximation, for the time discretization we consider the explicit Euler scheme.
