Discrete Flavour Symmetries: Non-zero θ₁₃ and Beyond

Models of leptonic mixing based on discrete flavour groups have
received a lot of attention over the past decade. I will discuss a
bottom up approach in which the knowledge of the leptonic mixing
angles is used to infer the underlying discrete flavour symmetries.
Some of the simplest symmetry groups supported by experiment as a
possible good first approximation to the data will be reviewed. The
status of the flavour symmetries after the recent discovery of
non-zero reactor angle will be discussed. I will also present some new
developments in the field in which the discrete flavour symmetries are
used to predict quark-lepton mass relations and neutrino mass
hierarchies beyond the leptonic mixing pattern.
