Certain homogeneous paracontact three-dimensional Lorentzian metrics
Abstract
In this paper, we study three-dimensional homogeneous paracontact metric manifolds for which the Reeb vector field of the underlying paracontact structure satisfies a nullity condition. We give example of paraSasakian and non-paraSasakian -manifolds. Finally, we exhibit explicit example of -Einstein manifolds.
