In this paper, we investigate conditions under which the quasi-stationary distribution for $X(t)$ exists and is unique, and any initial distribution supported in $S$ is in the domain of attraction of this quasi-stationary distribution. We further find five conditions which are equivalent to that the extinction time is uniformly bounded. As a consequence, we prove the van Doorn's conjecture in \\cite{VD2012}. And we can greatly improve theorem 1 in \\cite{VD2012}.", "revisions": [ { "version": "v1", "updated": "2014-10-07T08:26:53.000Z" } ], "analyses": { "subjects": [ "60J27", "60J80" ], "keywords": [ "quasi-stationary distribution", "markov processes", "attraction problem", "uniqueness", "van doorns conjecture" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1410.1638Z" } } }
