Trace Anomaly Inflation in Brane Induced Gravity
In the present letter we find that Starobinsky’s inflationary solution is also valid in the Dvali-Gabadadze-Porrati (DGP) model where a 3-brane is embedded in 5dimensional Minkowski bulk. We show that such a solution is typically not supported by the Self-Accelerated branch of the model, giving therefore a natural selection of the conventional branch of solutions. In the absence of brane induce...
متن کاملTrace anomaly and Hawking effect in 2D dilaton gravity theories
These notes summarize the content of two of our papers dealing with two-dimensional (2D) dilaton gravity theories [1,2]. Our presentation in Santa Margherita was essentially based on the first paper [1], whereas the content of the second one [2] was briefly sketched as work in progress. For sake of completeness it seems to us advisable to give a full account of the recent results of Ref. [2] in...
متن کاملCounterterms and dual holographic anomalies in CS gravity
The holographic Weyl anomaly associated to Chern-Simons gravity in 2n + 1 dimensions is proportional to the Euler term in 2n dimensions, with no contributions from the Weyl tensor. We compute the holographic energy-momentum tensor associated to ChernSimons gravity directly from the action, in an arbitrary odd-dimensional spacetime. We show, in particular, that the counterterms rendering the act...
متن کاملHamilton–Jacobi counterterms for Einstein–Gauss–Bonnet gravity
The on-shell gravitational action and the boundary stress tensor are essential ingredients in the study of black hole thermodynamics. We employ the Hamilton–Jacobi method to calculate the boundary counterterms necessary to remove the divergences and allow the study of the thermodynamics of Einstein–Gauss–Bonnet black holes.

متن کاملOne-loop counterterms in 2d dilaton-Maxwell quantum gravity
The renormalization structure of two-dimensional quantum gravity is investigated, in a covariant gauge. One-loop divergences of the effective action are calculated. All the surface divergent terms are taken into account, thus completing previous one-loop calculations of the theory. It is shown that the on-shell effective action contains only surface divergences. The off-shell renormalizability ...
