Depending on the local angular intensity of the electron lepton number carried by neutrinos, the conversion rate is \"fast,\" i.e., of the order of $\\sqrt{2}G_{\\rm{F}}(n_{\\nu_e}{-}\\,n_{\\bar\\nu_e})\\gg\\Delta m^2_{\\rm atm}/2E$. We present a novel approach to understand these phenomena: A dispersion relation for the frequency and wave number $(\\Omega,\\bf{K})$ of disturbances in the mean field of $\\nu_e\\nu_x$ flavor coherence.
