We show that a group G has Property T if and only if C * r (G) has Property T. In addition, we introduce and investigate relative Property T for C * -algebras. © 2014 Firuz Kamalov and Ho Hon Leung.enCreative Commons by-nc-nd Attribution License.C * -algebrasProperty TRelative property TArticleCopyright : 2014 Firuz Kamalov and Ho Hon Leung
