Abstract
Several simple dark energy models on the brane
are investigated. They are compared with corresponding
models in the frame of 4d Friedmann-Robertson-Walker
cosmology. For constraining the parameters of the models
considered, recent observational data, including SNIa ap-
parent magnitude measurements, baryon acoustic oscillation
results, Hubble parameter evolution data and matter den-
sity perturbations are used. Also, explicit formulas of the
so-called
state-finder
parameters in teleparallel theories are
found that could be useful to test these models and com-
pare Loop Quantum Cosmology and Brane Cosmology. The
conclusion is reached that a joint analysis as the one devel-
oped here allows to estimate, in a very clear way, possible
deviation of our cosmology from the standard Friedmann-
Robertson-Walker one
