求二阶有理常微分方程初等一阶不变量的半算法
A semi-algorithm to find elementary first order invariants of rational second order ordinary differential equations
摘要:
本文提出了一种基于Darboux型程序\cite{ManMac,firsTHEOps1,secondTHEOps1}求二阶有理常微分方程初等首次积分的方法。除了实际的计算考虑,该方法将能够告诉我们(达到一定的多项式次数),如果SOODE有一个基本的第一积分,并在积极的情况下,通过求积找到它。
英文摘要:
Here we present a method to find elementary first integrals of rational second order ordinary differential equations (SOODEs) based on a Darboux type procedure \cite{ManMac,firsTHEOps1,secondTHEOps1}. Apart from practical computational considerations, the method will be capable of telling us (up to a certain polynomial degree) if the SOODE has an elementary first integral and, in positive case, finds it via quadratures.
