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…
Brans-Dicke wormhole 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…
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…
Schwarzschild metrics and quasi-universes
A. G. Agnese, M. La Camera
The exterior and interior Schwarzschild solutions are rewritten replacing the usual radial variable with an angular one. This allows to obtain some results otherwise less apparent…
On 4-dimensional cosmological models locally embedded in a 5-dimensional Ricci-flat space
A. G. Agnese, M. La Camera
We employ a theorem due to Campbell to build some simple 4-dimensional cosmological models which originate from solutions describing waves propagating along the extra-dimension of…
Discretizing ups-Andromedae planetary system
A. G. Agnese, R. Festa
Starting from a previously stated hypothesis concerning the discretization of the orbits for periodic celestial motions, the mass of ups-Andromedae and the periods of its b- and d-…
