Number theory I.a - Algebraic number theory

MATH-482 / 5 credits

Teacher: Lüthi Manuel Werner

Language: English

Summary

Algebraic number theory is the study of the properties of solutions of polynomial equations with integral coefficients; Starting with concrete problems, we then introduce more general notions like algebraic number fields, algebraic integers, units, ideal class groups...

Content

  • Basics on rings and modules, lattices in R^n
  • Dedekind rings
  • The ring of integers of a number field
  • Application to Galois theory
  • Finiteness of the ideal class group
  • Dirichlet's units theorem
  • Applications
