Zajtsev, V. F. On discrete-group analysis of ordinary differential equations. (English. Russian original) Zbl 0794.58038 Sov. Math., Dokl. 37, No. 2, 403-406 (1988); translation from Dokl. Akad. Nauk SSSR 299, No. 3, 542-545 (1988). Application of discrete groups of transformations to investigation of ordinary differential equations is discussed in this paper. In particular, maximal discrete groups of point transformations and maximal discrete groups of special nonlocal transformations for some classes of equations of the form \(y''= Ax^ n y^ m (y')^ l\) are presented; the general solution of the equation \(y''= Ax^{-15/8} y(y')^{1/2}\) is found with the help of the transformations of these groups.
