Аннотация: We describe a method to generate nonlocal constants of motion for a special class of nonlinear ODEs. We employ the method of the generalized Sundman transformation to obtain certain new nonlocal first integrals of autonomous second-order ordinary differential equations belonging to the classification scheme developed by Painlevé and Gambier.

Ключевые слова: Sundman transformation, Painlevé –Gambier, symmetry, nonlocal first integrals, Jacobi equation.
