The quantum Boltzmann equations may be relevant for the leptogenesis scenario, in particular when the asymmetry is generated by the decays of nearly mass-degenerate right-handed neutrinos. We study the impact of such quantum effects in the so-called Minimal Lepton Flavour Violation framework, where the charged-lepton and the neutrino Yukawa couplings are the only irreducible sources of lepton-flavour symmetry breaking.
