Aperiodicity of the Hamiltonian Flow in the Thomas--Fermi
potential
(285K, Plain TeX)

ABSTRACT.  We prove an inequality which plays a central role in the
atomic energy asymptotics of large atoms. It is strong version
of the fact that the set of classical closed trajectories
in the Thomas--Fermi potential has measure 0.
