Signature of the interaction between dark energy and dark matter in galaxy clusters
E. Abdalla, L. R. Abramo, L. Sodre +1
We investigate the influence of an interaction between dark energy and dark matter upon the dynamics of galaxy clusters. We obtain the general Layser-Irvine equation in the presenc…

Entropy and holography constraints for inhomogeneous universes
Bin Wang, Elcio Abdalla, Takeshi Osada
We calculated the entropy of a class of inhomogeneous dust universes. Allowing spherical symmetry, we proposed a holographic principle by reflecting all physical freedoms on the su…

Evolving of a massless scalar field in Reissner--Nordström Anti--de Sitter spacetimes
B. Wang, C. Molina, E. Abdalla
We investigate the evolution of a scalar field propagating in Reissner--Nordström Anti--de Sitter spacetime. Due to the characteristic of spacetime geometry, the radiative tails as…
