4 Cosmological Spacetimes with Λ > 0

This paper is based on a talk given by the author at the BEEMFEST, held at the University of Missouri, Columbia, in May, 2003. It was indeed a great pleasure and priviledge to participate in this meeting honoring John Beem, whose many oustanding contributions to mathematics, and leadership in the field of Lorentzian geometry has enriched so many of us. In this paper we present some results, bas...

Non-existence of Black Holes in Certain Λ < 0 Spacetimes

Assuming certain asymptotic conditions, we prove a general theorem on the non-existence of static regular black holes in spacetimes with a negative cosmological constant, given that the fundamental group of space is infinite. We use this to rule out the existence of regular negative mass AdS black holes with Ricci flat scri. For any mass, we also rule out a class of conformally compactifiable s...

Clifford Algebroids and Nonholonomic Spinor Deformations of Taub–NUT Spacetimes

In this paper we examine a new class of five dimensional (5D) exact solutions in extra dimension gravity possessing Lie algebroid symmetry. The constructions provide a motivation for the theory of Clifford nonholonomic algebroids elaborated in Ref. [1]. Such Einstein–Dirac spacetimes are parametrized by generic off–diagonal metrics and nonholonomic frames (vielbeins) with associated nonlinear c...
