On global transformations of ordinary differential equations of the second order

Czechoslovak Mathematical Journal
Similarity:
The paper describes the general form of an ordinary differential equation of the second order which allows a nontrivial global transformation consisting of the change of the independent variable and of a nonvanishing factor. A result given by J. Aczél is generalized. A functional equation of the form is solved on for ,
The only global contact transformations of order two or more are point transformations.
