Abstract
The linearization problem of a secondorder ordinary differential
equation by the generalized Sundman transformation was considered
earlier by Duarte, Moreira and Santos using the Laguerre form.
The results obtained in the present paper demonstrate that their
solution of the linearization problem for a secondorder ordinary
differential equation via the generalized Sundman transformation
is not complete. We also give examples which show that the
Laguerre form is not sufficient for the linearization problem via
the generalized Sundman transformation.
Key words:
linearization problem; generalized Sundman transformations; nonlinear secondorder ordinary differential equations.
