论文摘要
我们提出了一种算法，如果可能的话，将带有根部函数系数的给定ODE或PDE转换为具有理性系数的算法或通过变量的合理变化。它也适用于线性ODES系统。它基于以前关于重新培训代数品种的工作。
We present an algorithm that transforms, if possible, a given ODE or PDE with radical function coefficients into one with rational coefficients by means of a rational change of variables. It also applies to systems of linear ODEs. It is based on previous work on reparametrization of radical algebraic varieties.
