Abstract We extend the framework of modular invariant supersymmetric theories to encompass invariance under more general discrete groups Γ, that allow the presence of several moduli and make connection with the theory of automorphic beer button down shirts for men forms.Moduli span a coset space G/K, where G is a Lie group and K is a compact subgroup of G, modded out by Γ.For a general choice of G, K, Γ and a generic matter content, we explicitly construct a minimal Kähler potential and a general superpotential, for both rigid and local N soderhamn ottoman cover $$ mathcal{N} $$ = 1 supersymmetric theories.

We also specialize our construction to the case G = Sp(2g, ℝ), K = U(g) and Γ = Sp(2g, ℤ), whose automorphic forms are Siegel modular forms.We show how our general theory can be consistently restricted to multi-dimensional regions of the moduli space enjoying residual symmetries.After choosing g = 2, we present several examples of models for lepton and quark masses where Yukawa couplings are Siegel modular forms of level 2.
