section = "C - Gravitation and cosmology"
talkabstract = "Brane dark energy cosmologies, leading to various possible evolutions of our universe, are investigated.
The discussion shows that while all these models can be made arbitrarily close to the
standard CDM cosmology at present, their future evolutions can be very dierent, even diverge
with time in a number of ways. This includes asymptotic de-Sitter evolution, Little Rip with dissolution
of bound structures, and various possible singularities, as the Big Rip, a sudden future
singularity (Type II), and Type III and Type IV cases. Specifically, the interesting eects coming
from the brane tension are investigated. Thus, it is shown that the Little Rip occurs faster on the
brane model than in usual FRW cosmology. And in the asymptotic de-Sitter regime the in
uence of
the brane tension leads to a deviation of the value of the eective cosmological constant from that
corresponding to ordinary dark energy. As a consequence, the value of the inertial force from the
accelerating expansion can greatly exceed the corresponding inertial force in ordinary cosmological
models."
