Nosé-Thermostated Mechanical Systems on the n-Torus

Abstract

Let $H(q,p)=\frac{1}{2}|p{|}^2+V(q)$ be an $n$-degree of freedom $C^r$ mechanical Hamiltonian on the cotangent bundle of the $n$-torus where $r>2n+2$. When the metric $|\ast |$ is flat, the Nosé-thermostated system associated to $H$ is shown to have a positive-measure set of invariant tori near the infinite temperature limit. This is shown to be true for all variable mass thermostats similar to Nosé's, too. These results complement results of Legoll, Luskin & Moeckel and the author.
