Transforming ODEs and PDEs with radical coefficients into rational coefficients

by   Jorge Caravantes, et al.

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.
