The Cardy-Verlinde equation in a spherical symmetric gravitationalcollapse.
No full textThe Cardy-Verlinde formula is analyzed in the contest of the gravitational collapse. Starting from the holographic principle, we show how the equations for a homogeneous and isotropic gravitational collapse describe the formation of the black hole entropy. Some comments on the role of the entangled entropy and the connection with the c-theorem are made
A non-minimally coupled theory of gravitation with torsion
No full textWe extend to a Riemann-Cartan spacetime the Einstein equations for a Klein-Gordon scalar field, which is non-minimally
coupled to the underlying geometry. We show in which case it is possible to avoid the initial singularity and get inflationary
