Add to ORKGThe inverse problem of the calculus of variations asks for necessary and sufficient conditions that a given system of second order ordinary differential equations should be the Euler-Lagrange equations of a regular Lagrangian function. In 1941 Douglas [3] gave an exhaustive and apparently complet
