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.
