In this paper, we will analyze the effects of superlight braneworld perturbative modes on clustering galaxies. present manuscript, use Boltzmann and Tsallis statistical approaches to study large distance modification gravity in braneworld. The impact modified potential galaxies is analyzed both approaches. infinities associated with Newtonian point mass approximation models removed using analyt...

The purpose of this brief report is to present some results of our on-going project on the asymptotic behaviour of braneworld-type solutions on approach to their possible finite ‘time’ singularities. Cosmological singularities in such frameworks have served as means to attack the cosmological constant problem (see and references therein). The main mathematical tool of our analysis is the method...

We consider the future dynamics of a transient phantom dominated phase of the universe in LQC and in the RS braneworld, which both have a non-standard Friedmann equation. We find that for a certain class of potentials, the Hubble parameter oscillates with simple harmonic motion in the LQC case and therefore avoids any future singularity. For more general potentials we find that damping effects ...
