Apostol’s Modular Functions and Dirichlet Series in Number Theory [Tom M. Apostol, 1990] is a graduate text covering topics such as elliptic functions, modular functions, approximation theorems and general Dirichlet series. It relies on complex analysis, winding numbers, the Riemann ζ function and Laurent series. We have formalised several chapters and can comment on the sort of gaps found in pedagogical mathematics. Proofs are available from https://github.com/Wenda302/Number_Theory_ITP2024.
