Summary of Model Predictions for $U_{e3}$

Abstract

We present a short discussion on the expected magnitude of $|U_{e3}|$ in the context of various scenarios proposed to describe neutrino masses and mixing. Generic expectation is relatively large ($>0.05$) values for $\ue3$ which occur in many well-motivated theoretical scenarios and models.
