摘要： 研究一类带时滞项的二阶奇异摄动微分方程的自适应网格算法。首先,通过积分变换,得到一个带时滞项的一阶奇异摄动Volterra积分微分方程;其次,利用向后差分和左矩形公式,在任意网格上构造一个一阶有限差分格式,利用离散的Grönwall不等式,给出离散格式的先验误差估计,并基于网格等分布原理设计一个自适应移动网格算法,在该自适应网格下,证明离散格式为一阶一致收敛;最后,数值实验结果验证理论分析。

Abstract: An adaptive grid algorithm for a second-order singularly perturbed delay boundary value problem is studied. Firstly, by integral transformation, the problem is rewritten into a first-order singularly perturbed delay Volterra integral differential equation. Secondly, a first-order finite difference format is constructed on an arbitrary mesh by using the backward difference and left rectangle formula. Using the discrete Grönwall inequality, a prior error estimation of the proposed discretization scheme is derived and an adaptive moving grid algorithm is designed based on the mesh equidistribution principle. It is proved that our proposed adaptive moving grid method is first-order uniformly convergent. Finally, some numerical results are given to support our presented theoretical result.

Key words: singularly perturbed, delay differential equation, monitor function, error estimation
