Ks. Govinder et Pgl. Leach, SOLUTION OF THE NONLINEAR DIFFERENTIAL-EQUATION Y''+P(X)Y=Q(M)(X) Y(2M-1)/, Transactions of the Royal Society of South Africa, 49, 1994, pp. 175-184
A wider class of solutions to the nonlinear differential equation y(n)
+ p (x) y = q(m) (x)/y(2m-1) than that given by Reid is obtained. In
the process the relationships between Kummer-Liouville transformations
and generalized canonical transformations and autonomous Hamiltonian
systems and Lie point symmetries are uncovered.
