Aspects of Modular Flavor Symmetries

Abstract

Modular flavor symmetries refers to scenarios in which fermion masses respect modular symmetries. Such scenarios have been studied in the bottom-up approach and have an explicit realization in string theory. They rely on the remarkable properties of vector-valued modular forms.
