Description
Modular flavor symmetries in supersymmetric models have been proposed as a new way to address the flavor problem. It is known that they can emerge from string compactifications. We discuss this connection in detail, and show how the congruence subgroups of SL(2,Z), which underlie many modular flavor symmetries, emerge from stringy duality symmetries by orbifolding. We show that, at least in the Z3 orbifold, the string selection rules can be understood as discrete remnants of continuous gauge symmetries.
