摘要: The classical tools which ensure the completeness of both, vector fields and second order differential equations for mechanical systems, are revisited. Possible extensions in three directions discussed: infinite dimensional Banach (and Hilbert) manifolds, Finsler metrics pseudo-Riemannian spaces, latter including links with some relativistic spacetimes. Special emphasis is taken cleaning up known techniques, statement open questions exploration prospective frameworks.
