摘要:

通过APLAN语言中的APS构建了一个新程序。该程序求解区间$[a, b]$上初始化点处具有多项式系数和正则奇点的$k$阶线性微分方程的初值问题,并计算给定阶数$n$的代数多项式$y_n$。为此程序建立了Lanczos $\tau$-方法的新算法,证明了该算法上初值问题解$y_n$的存在性,并证明了在初值问题解的$k$阶导数精度上的最优性。

英文摘要:

A new procedure is constructed by means of APS in APLAN language. The procedure solves the initial-value problem for linear differential equations of order $k$ with polynomial coefficients and regular singularity in the initialization point in the interval $[a, b]$ and computes the algebraic polynomial $y_n$ of given order $n$. A new algorithm of Lanczos $τ$-method is built for this procedure, the solution existence $y_n$ of the initial-value problem proved on this algorithm and also is proved the optimality by precision of order $k$ derivative of the initial-value problem solution.
