Competencies / intended learning achievements

Upon completion of this module, the students have studied extensions of a number system through p-adic numbers which are fundamental for number theory. In particular, they have studied their main properties and some simple applications. They are able to name and to prove the essential statements of the lecture as well as to classify and to explain the connections.

By completing the given exercises, the students have developed a skilled, precise and independent handling of the terms, propositions and techniques taught in the lecture. In addition, they have learnt how to apply these techniques to new problems, analyze them and develop solution strategies independently or by team work.


  • F. Lorenz: Einführung in die Algebra II,
  • N. Koblitz: p-adic Numbers, p-adic Analysis, and Zeta-Functions,
  • I.B. Fenseko, S.V. Vostokov: Local Fields and their Extensions.
