Algebraic Number Theory I
Semester
WiSe 2024 / 25

Lecturer
Klaus Künnemann

Type of course (Veranstaltungsart)
Vorlesung

German title
Algebraische Zahlentheorie I

Contents
This course gives an introduction to Algebraic Number Theory. Together with the course on Algebraic
Geometry this course can serve as a basis for further specialization in the area of Arithmetic
Geometry. We treat number fields, rings of algebraic integers, Dedekind domains, Minkowski's lattice
point theory, finiteness of class numbers, Dirichlet's unit theorem, ramification theory, local
fields, valuations, and the product formula.
