Szarek [Stud. Math. 189 (2008), {\\S} 4] have discussed the relationship between two important notions concerning Markov semigroups: the asymptotic strong Feller property and the e-property, asserting that the former property implies the latter one. In this very short note we rectify this issue exhibiting a simple example of a Markov-Feller semigroup enjoying the asymptotic strong Feller property, for which the e-property is not satisfied. (See also the comment on a connection between the asymptotic strong Feller property and the e-property by T. Szarek, D. Worm [ETDS 32 (2012), {\\S} 1]). Additionally we give a very simple example - in comparing with the one given by T. Szarek [Stud. Math. 189 (2008), {\\S} 4] - showing that also the converse implication does not hold.", "revisions": [ { "version": "v1", "updated": "2013-08-22T19:46:04.000Z" } ], "analyses": { "subjects": [ "37A30", "60J25" ], "keywords": [ "asymptotic strong feller property", "markov-feller semigroup", "e-property", "important notions concerning markov semigroups", "simple example" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013arXiv1308.4967J" } } }
