The Laplace transform of transition probability function for birth-death processes with two-type catastrophes are is successfully expressed with the Laplace transform of transition probability function of the birth-death processes without catastrophe. The first effective catastrophe occurrence time is considered. The Laplace transform of its probability density function, expectation and variance are obtained.", "revisions": [ { "version": "v1", "updated": "2024-04-07T15:04:00.000Z" } ], "analyses": { "subjects": [ "60J27" ], "keywords": [ "two-type catastrophes", "laplace transform", "transition probability function", "first effective catastrophe occurrence time", "general birth-death processes" ], "note": { "typesetting": "TeX", "pages": 18, "language": "en", "license": "arXiv", "status": "editable" } } }
