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

Students

  • Have learned the fundamentals of classical number theory,
  • recognize the cross connections to methods of algebra and calculus,
  • have practiced mathematical ways of working (developing mathematical intuition and its formal justification, training the ability to abstract, reasoning),
  • have improved their oral communication skills in exercises by practicing free speech in front of an audience and in 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.
