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-…
Black-body laws derived from a minimum knowledge of Physics
A. G. Agnese, M. La Camera, E. Recami
Starting from the knowledge of the four fundamental quantities length L, mass M, time T, absolute temperature and accepting the validity of Gauss's law in all dimensions, we ge…
