Algebraic aspects of transformations with an application to differential equations. (English) Zbl 0957.34008
In the paper, a historical and a general algebraic approach of transformations with an application to linear differential equations is given. Moreover, the global equivalence of two linear \(n\)th-order equations is defined and a criterion of equivalence is described.
