Description
Ever since Harrison, Perkins and Scott suggested that the neutrino mixing data could be approximated by the tri-bimaximal mixing matrix, there have been many proposals to explain its structure in terms of a discrete family symmetry. In this talk we discuss two classes of models - direct and indirect - which realise the effective neutrino flavour symmetry in different ways. We illustrate both possibilities in explicit models based on A4 and S4.
