Abstract
The linearization problem for nonlinear secondorder
ODEs to the Laguerre form by means of generalized Sundman
transformations (Stransformations) is considered, which has been
investigated by Duarte et al. earlier. A characterization of these
Slinearizable equations in terms of first integral and procedure
for construction of linearizing Stransformations has been given
recently by Muriel and Romero. Here we give a new characterization of
Slinearizable equations in terms of the coefficients of ODE and
one auxiliary function. This new criterion is used to obtain the
general solutions for the first integral explicitly, providing a
direct alternative procedure for constructing the first integrals
and Sundman transformations. The effectiveness of this approach is
demonstrated by applying it to find the general solution for
geodesics on surfaces of revolution of constant curvature in a
unified manner.
Key words:
linearization problem; generalized Sundman transformations; first integrals; nonlinear secondorder ODEs.
