AI总结:

本文提出一种新颖的射线法,用于求解二阶常微分方程的两点边值问题。通过猜测初始条件并积分微分方程得到初始值问题解,再利用简单迭代公式修正初始条件,直至满足第二个边界条件。

摘要:

本文提出了一种新颖的射线法,用于求解二阶常微分方程的两点边值问题。该方法的工作流程如下:首先,对初始条件进行猜测,并对微分方程进行积分以获得初始值问题的解;然后,利用解的终端值在一个简单的迭代公式中修正初始条件;该过程重复进行,直到满足第二个边界条件。迭代公式是通过一个满足两个边界条件且最小化自身与初始值问题解差值H1半范数的辅助函数推导得出的。

英文摘要:

This paper presents a novel shooting method for solving two-point boundary value problems for second order ordinary differential equations. The method works as follows: first, a guess for the initial condition is made and an integration of the differential equation is performed to obtain an initial value problem solution; then, the end value of the solution is used in a simple iteration formula to correct the initial condition; the process is repeated until the second boundary condition is satisfied. The iteration formula is derived utilizing an auxiliary function that satisfies both boundary conditions and minimizes the H1 semi-norm of the difference between itself and the initial value problem solution.
