Abstract
|
The
space of
-jets of a real function
of one real variable
admits the structure of a sub-Riemannian manifold, which then has an
associated Hamiltonian geodesic flow, and it is integrable. As in any
Hamiltonian flow, a natural question is the existence of periodic solutions. Does
have periodic geodesics? This study will find the action-angle coordinates in
for the geodesic flow and demonstrate that geodesics in
are
never periodic.
