Framework for encoding modular forms and automorphic representations into spectral operators. For f (τ) = Σ aₙqⁿ of weight k and level N, constructs Hf whose spectral properties reflect the arithmetic of Fourier coefficients. Key innovations: Weight-Scaling Correspondence (modular weight → fractal dimension), Hecke-Spectral Isomorphism (Hecke eigenvalues → operator eigenvalues), Level Structure Encoding via boundary conditions. Applications to Ramanujan bounds, Sato-Tate distribution, modularity, and the Langlands program.
