# Introduction to the Theory of Algebraic Functions of One Variable

Share this page
*C. C. Chevalley*

This classical book, written by a famous French
mathematician in the early 1950s, presents an approach to algebraic
geometry of curves treated as the theory of algebraic functions on the
curve. Among other advantages of such an approach, it allowed the
author to consider curves over an arbitrary ground field. Among topics
discussed in the book are the theory of divisors on a curve, the
Riemann–Roch theorem, \(p\)-adic completion, extensions
of the fields of functions (covering theory) and of the fields of
constants, and the theory of differentials on a curve. The last
chapter, which is more analytic in flavor, treats the theory of
Riemann surfaces.

Prerequisites for reading are minimal and include only an advanced
undergraduate algebra course.
