More precisely, given Ta=inf{t>0:Xt∉. Under general conditions, e.g. absolute continuity of the transition semigroup of the unkilled Lévy process, we prove that the killed semigroup is a compact operator. Thus, we prove stronger results in view of the exponential ergodicity and estimates of the speed of convergence. Our results are presented in a Lévy processes setting but are well applicable for Markov processes in a finite interval under information about Lebesgue irreducibility of the killed semigroup and that the killed process is a double Feller process. For example, this scheme is applicable to a work of Pistorius.<br />"}],"date_created":"2022-09-14T05:15:00Z","status":"public","doi":"http://dx.doi.org/10.1214/ECP.v19-3006","page":"1-9","date_updated":"2022-09-14T05:15:06Z","type":"journal_article","volume":19,"publisher":"Institute of Mathematical Statistics (IMS)","_id":"33361","language":[{"iso":"eng"}],"title":"Exponential ergodicity of killed Lévy processes in a finite interval","year":"2014","user_id":"85821","author":[{"first_name":"Martin","id":"48880","last_name":"Kolb","full_name":"Kolb, Martin"},{"last_name":"Savov","full_name":"Savov, Mladen","first_name":"Mladen"}]}
