We study a specific texture of the neutrino mass matrix, namely the models with one $2\times 2$ subdeterminant equal to zero. We carry out a complete phenomenological analysis with all possible relevant correlations. Every pattern of the six possible ones is found able to accommodate the experimental data, with three cases allowing also for non-invertible mass matrices. We present symmetry realizations for all the models.

The Triadic Texture: Neutrino Predictions, Viable Vacuum, and Phenomenological Constraints
A new neutrino mass matrix texture under A4 x multiple Z symmetries predicts normal hierarchy, theta23 octant, and bounds on phases and masses in a seesaw model.
