Orbitas frenadas en sistemas mecánicos finslerianos

Given a mechanical system (M,K,U) where M is a n-dimensional variety and the kinetic and potential energy K and U are three times differentiable, let E0 be a potential energy value such that {X ϵ M|U(x) ≤ E0} is homeomorphic to the n-dimensional disk, and its border B is the E0-equipotential surface...
