After establishing the existence and uniqueness of a global weak solution via the martingale approach under very mild conditions, the paper next proves the strong Feller property for regime-switching stochastic damping Hamiltonian systems by the killing technique together with some resolvent and transition probability identities. The commonly used continuity assumption for the switching rates $q_{kl}(\\cdot)$ in the literature is relaxed to measurability in this paper. Finally the paper provides sufficient conditions for exponential ergodicity and large deviations principle for regime-switching stochastic damping Hamiltonian systems. Several examples on regime-switching van der Pol and (overdamped) Langevin systems are studied in detail for illustration.", "revisions": [ { "version": "v1", "updated": "2020-05-21T15:38:29.000Z" } ], "analyses": { "subjects": [ "60J60", "60J27", "34D25" ], "keywords": [ "large deviations principle", "strong feller property", "exponential ergodicity", "state-dependent switching", "regime-switching stochastic damping hamiltonian systems" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
