This is an introduction to the arithmetic theory of modular functions and modular forms, with a greater emphasis on the geometry than most accounts.


  1. Preliminaries
  2. Elliptic modular curves as Riemann surfaces
  3. Elliptic functions
  4. Modular functions and modular forms
  5. Hecke operators
  6. The modular equation for Gamma_0(N)
  7. The canonical model of X_0(N) over Q
  8. Modular curves as moduli varieties
  9. Modular forms, Dirichlet series, and functional equations
  10. Correspondences on curves; the theorem of Eichler and Shimura
  11. Curves and their zeta functions
  12. Complex multiplication for elliptic curves


The algebra and complex analysis usually covered in advanced undergraduate or first-year graduate courses.
