Linear versus nonlinear stability in Hamiltonian systems

Research output: Chapter in Book/Report/Conference proceedingChapterAcademicpeer-review

Abstract

The stability of periodic solutions of time-independent Hamiltonian systems is often studied by linearization techniques. In the case of two degrees of freedom near stable equilibrium this is a correct procedure, in the case of three or more degrees of freedom we present some counterexamples. The case of the classical Fermi-Pasta-Ulam chain with cubic and quartic interactions illustrates the instability phenomenon.
