The role of different non-equilibrium processes on the early
Universe is investigated.
The effects of non-equilibrium processes,
like additional particle
decays, neutrino oscillations, particle creation by a
varyable scalar field,
formation of a scalar condensate, generation or
presence of a lepton
asymmetry, etc. on reheating, baryogenesis and
Big Bang Nucleosynthesis is
studied analytically and numerically.
