DESCRIPTION:The precision reached in neutrino oscillation measurements sha
 rpens the question of why lepton masses and mixing differ so markedly from
  those of quarks. I discuss here three complementary approaches to the fla
 vour problem: non-Abelian discrete symmetries\, modular invariance\, and q
 uark–lepton mixing relations. Simple mixing textures provide useful lead
 ing order descriptions\, but require controlled corrections\, in particula
 r to account for the nonzero reactor angle. Modular invariance constrains 
 Yukawa couplings through their dependence on a complex modulus and offers 
 a different organisation of flavour breaking. Finally\, CKM-related constr
 uctions illustrate how a Cabibbo-sized contribution to lepton mixing can e
 merge\, while also exposing the additional assumptions required to connect
  the two sectors.\n \nhttps://bnl.zoomgov.com/j/1653048131?pwd=fkT0TgSQn5
