Abstract. We present some remarks on the existence and the properties of Lie point
symmetries of finite dimensional dynamical systems expressed either in
NewtonLagrange or in Hamilton form. We show that the only Lie symmetries
admitted by NewtonLagrangetype problems are essentially linear symmetries,
and
construct the most general problem admitting such a symmetry. In the case of
Hamilton problems, we discuss the differences and the relationships between the
existence of timeindependent Lie point symmetries and the invariance
properties
of the Hamiltonian under coordinate transformations
