Neutrino Theory: Some Recent Developments

Abstract

Selected topics in neutrino theory are discussed, including tribimaximal mixing and its A_4 realization, variations of the seesaw mechanism allowing for observable deviations from unitarity of the neutrino mixing matrix, and the radiative generation of neutrino mass from dark matter.
