We establish existence and uniqueness of this process and analyze its properties. In particular, we show global time-space boundedness of the population density and, using a constructed Foster-Lyapunov-type function, we study return times to certain level sets of tempered configurations. We find also sufficient conditions that the degenerate invariant distribution is unique for the considered process.", "revisions": [ { "version": "v1", "updated": "2019-03-14T17:58:15.000Z" } ], "analyses": { "subjects": [ "60G55", "60J25", "82C21" ], "keywords": [ "spatial birth-and-death process", "density dependent fecundity regulation mechanism", "global time-space boundedness", "degenerate invariant distribution", "study return times" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
