Therefore the effects considered in [1] are a particular case of the parametric resonance in neutrino oscillations. The existence of strong enhancement peaks in transition probability P rather than the condition P=1 is of physical relevance. We comment on possible realizations and implications of the parametric enhancement of neutrino oscillations.8 pages, latex, 2 figures, typos correctedHigh Energy Physics - PhenomenologyAstrophysicsHigh Energy Physics - Experimenttext
