More precisely, for any observable $G$, it is demonstrated that the ensemble under $G$ in long time average converges to that over one time period $T$, and that the probability measure induced by the probability density function describing the ensemble at time $t$ weakly converges to the average of the probability measures over time $T$. And we extend the result to almost periodic cases. The key to the proof is based on the {\\it {Riemann-Lebesgue lemma in time-average form}} generalized in the paper. %This work contributes to the comprehension of the statistical mechanics of Hamiltonian systems subject to disturbances.", "revisions": [ { "version": "v1", "updated": "2023-11-24T01:57:42.000Z" } ], "analyses": { "keywords": [ "integrable hamiltonian systems", "periodic transitions", "statistical ensembles", "long time average converges", "probability measure" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
