Contents

  • Fundamental theorem of arithmetic,
  • g-adic expansion and divisibility,
  • elementary theory of primes,
  • Examples of public-key cryptographic methods,
  • Diophantine equations,
  • Modular arithmetic, power residues, reciprocity laws.

Qualification Goals

The students shall

  • learn the basics of classical number theory,
  • recognize the links to methods from algebra and analysis,
  • practice mathematical working methods (development of mathematical intuition and its formal justification, training of abstraction and formulating proofs),
  • improve their oral communication skills in the exercises by practicing free speech in front of an audience and during discussion.

Prerequisites

None. The competences taught in the following modules are recommended: either Foundations of Mathematics and Linear Algebra I and Linear Algebra II or Basic Linear Algebra, either Analysis I and Analysis II or Basic Real Analysis.
