摘　　要：We study the near horizon geometry of both static and stationary extremal Oliva Tempo Troncoso(OTT)black holes. For each of these cases, a set of consistent asymptotic conditions is introduced. The canonical generator for the static configuration is shown to be regular. For the rotating OTT black hole, the asymptotic symmetry is described by the time reparametrization, the chiral Virasoro and centrally extended u(1) Kac-Moody algebras.We study the near horizon geometry of both static and stationary extremal Oliva Tempo Troncoso(OTT)black holes.
