Ergodic solutions via ergodic sequences

Nonlinear Analysis: Theory, Methods & Applications, 2000
It is known (G. H.~Meisters, Z.~Opial, and A. M.~Fink) that the existence of almost-periodic solutions to ordinary differential equations is equivalent to the fact that the restriction of a bounded solution to some discrete subgroup of reals is almost-periodic. There are results of this kind [see, e.g., \textit{A.

Ergodicity and Ergodic Points

2004
The problem of determining which sets are visited with defined frequency by the motions of a dynamical system (Ω, S) can be satisfactorily solved in the case of particularly simple systems; for instance in the case in which \(S = {S_{{t_0}}}\) and (S t )t∈ℝ is a Hamiltonian flow which is analytically integrable on a region W ⊂ ℝ2r and Ω = W, cf ...

Continuously broken ergodicity

The Journal of Chemical Physics, 2007
A system that is initially ergodic can become nonergodic, i.e., display “broken ergodicity,” if the relaxation time scale of the system becomes longer than the observation time over which properties are measured. The phenomenon of broken ergodicity is of vital importance to the study of many condensed matter systems.
