Cosmology

(i) neutrino dark energy

We have shown that a simple coupled system of a variable vacuum

term anda gas of relic neutrinos may account not only for a right

amount of dark energy at present, but also for a near coincidence

between the matter and dark-energy densities to hold over a significantportion of the history of the universe [R. Horvat, JCAP0601(2006)015].

(ii) holographic dark energy

(iii) renormalization-group running cosmology
