Entropy and Mass Bounds of Kerr-de Sitter Spacetimes
A. M. Ghezelbash, R. B. Mann
We consider Kerr-de Sitter spacetimes and evaluate their mass, angular momentum and entropy according to the boundary counterterm prescription. We provide a physicall interpretatio…
Atiyah-Hitchin M-Branes
A. M. Ghezelbash, R. B. Mann
We present new M2 and M5 brane solutions in M-theory based on transverse Atiyah-Hitchin space and other self-dual geometries. One novel feature of these solutions is that they have…
New Reducible Five-brane Solutions in M-theory
R. Clarkson, A. M. Ghezelbash, R. B. Mann
We construct new M-theory solutions of M5 branes that are a realization of the fully localized ten dimensional NS5/D6 and NS5/D5 brane intersections. These solutions are obtained b…
Mass, Action and Entropy of Taub-Bolt-dS Spacetimes
R. Clarkson, A. M. Ghezelbash, R. B. Mann
We apply a recent proposal for defining conserved mass in asymptotically de Sitter spacetimes to the class of Taub-Bolt-dS spacetimes. We compute the action, entropy and conserved…
Two Dimensional Quantum Gravity Coupled to Matter
R. B. Mann
A classical two dimensional theory of gravity which has a number of interesting features (including a Newtonian limit, black holes and gravitational collapse) is quantized using co…
