  • ideals and ideal class groups,
  • Ideals as geometric lattices,
  • finiteness of the ideal class group.

Competencies / intended learning achievements

Upon completion of this module, the students have studied the extension of a number system through quadratic number fields which is fundamental for number theory. They also have studied the rings contained in quadratic number fields as well as 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.
