One may be viewed as describing how two competing species invade if they occupy an initial region, the other describes the dynamical process of a new competitor invading into the habitat of a native species. For simplicity, it is assumed that the environment is radially symmetric. The main purpose of this article is to understand the asymptotic behavior of competing species spreading via a free boundary. We derive some sufficient conditions for species spreading success and spreading failure. Moreover, when spreading successfully, we provide the long time behavior of solutions.", "revisions": [ { "version": "v1", "updated": "2015-04-10T08:18:15.000Z" } ], "analyses": { "subjects": [ "35K51", "35R35", "92B05", "35B40" ], "keywords": [ "free boundary problems", "diffusive competition system", "sign-changing coefficients", "higher dimension", "higher space dimension" ], "note": { "typesetting": "TeX", "pages": 26, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015arXiv150402580Z" } } }
