CONTENT

Places,valuation rings and discrete valuations of a function field; the rational function field; divisors, Weil different adeles, genus; Riemann-Roch Theorem and its consequences; extensions of function fields, ramification, Hurwitz genus formula; constant field extensions, Galois extensions, Kummer and Artin-Schreier extensions.

LEARNING OUTCOMES

  • - discuss the basic notions of the theory, like places, divisors, Riemann-Roch spaces, and genus of a function field.
  • - recall the main results, centered around the Riemann-Roch theorem.
  • - recall the notions of ramification and splitting in extensions of function fields.
  • - apply these concepts in specific cases, in particular fields of small genus.
