Generalized Second Law of Thermodynamics in Extended Theories of Gravity

M. Akbar

By employing the general expression of temperature $T_{h} = ∣ κ ∣/2 π = \frac{1}{2 π r ~ _{A}} (1 - \frac{r ~ ˙ _{A}}{2 H r ~ _{A}})$ associated with the apparent horizon of…

Ricci Solitons and Einstein-Scalar Field Theory

M M Akbar, E Woolgar

B List has recently studied a geometric flow whose fixed points correspond to static Ricci flat spacetimes. It is now known that this flow is in fact Ricci flow modulo pullback by…

Viscous Cosmology and Thermodynamics of Apparent Horizon

M. Akbar

It is shown that the differential form of Friedmann equations of FRW universe can be recast as a similar form of the first law, $T_{h} d S_{h} = d E + W d V$ , of thermodynamics at the a…

Classical Boundary-value Problem in Riemannian Quantum Gravity and Taub-Bolt-anti-de Sitter Geometries

M. M. Akbar

For an $S U (2) \times U (1)$ -invariant $S^{3}$ boundary the classical Dirichlet problem of Riemannian quantum gravity is studied for positive-definite regular solutions of the Einstein…
