4D modular flavor symmetric models inspired by higher dimensional theory

We study a scenario to derive four-dimensional modular flavor symmetric models from higher dimensional theory by assuming the compactification consistent with the modular symmetry. In our scenario, wavefunctions in extra dimensional compact space are modular forms. That leads to constraints on combinations between modular weights and ${\mathrm{\Gamma }}_N$ (${\mathrm{\Gamma }}_N^{\mathrm{\prime }})$ representations of matter fields. We also present illustrating examples.
