Time-dependent extra dimension and higher-dimensional modifications to the matter content in FRW spacetimes
M. La Camera
In this work we suggest that higher-dimensional modifications to the matter content in FRW spacetimes can be obtained not only, as first considered by Ponce de Leon, referring to "…
Cosmological solutions in the brane-bulk system
Mario La Camera
In this work we find cosmological solutions in the brane-bulk system starting from a 5-D line element which is a simple extension, for cosmological applications, of the pioneering…
Wormhole solutions in the Randall-Sundrum scenario
M. La Camera
In the simplest form of the Randall-Sundrum model, we consider the metric generated by a static, spherically symmetric distribution of matter on the physical brane. The solution to…
Traceless stress-energy and traversable wormholes
A. G. Agnese, M. La Camera
A one-parameter family of static and spherically symmetric solutions to Einstein equations with a traceless energy-momentum tensor is found. When the nonzero parameter lies in…
Black hole horizon and space-time foam
A. G. Agnese, M. La Camera
We introduce, by means of the Brans-Dicke scalar field, space-time fluctuations at scale comparable to Planck length near the event horizon of a black hole and examine their dramat…
Kerr-AdS and Kerr-dS solutions revisited
A. G. Agnese, M. La Camera
We reconsider the Kerr metric with cosmological term imposing the condition that the angular velocity of the dragging of the inertial frames vanishes at spatial boundaries.…
