    Nonlocal Constants of Motions of Equations of Painlevé – Gambier Type and Generalized Sundman Transformation
    2022, Vol. 18, no. 1, pp.  103-118
    Abstract
    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.
