MT4519 Number Theory

Academic year

2025 to 2026 Semester 2

Key module information

SCOTCAT credits

15

The Scottish Credit Accumulation and Transfer (SCOTCAT) system allows credits gained in Scotland to be transferred between institutions. The number of credits associated with a module gives an indication of the amount of learning effort required by the learner. European Credit Transfer System (ECTS) credits are half the value of SCOTCAT credits.

SCQF level

SCQF level 10

The Scottish Credit and Qualifications Framework (SCQF) provides an indication of the complexity of award qualifications and associated learning and operates on an ascending numeric scale from Levels 1-12 with SCQF Level 10 equating to a Scottish undergraduate Honours degree.

Intended learning outcomes

  • Extend a basic knowledge of modular arithmetic to more advanced topics such as primitive roots and quadratic residues, as well as stating and proving many results concerning these concepts
  • Understand the theory of finite and infinite continued fractions, and apply this knowledge to find good rational approximations of algebraic and transcendental numbers
  • Apply ideas from the above topics to analyse famous equations such as the sum of two/three/four squares, Pell¿s equations, and special cases of Fermat's Last Theorem
  • Analyse the role that number theory plays in many areas of mathematics (such as cryptography, analysis, abstract algebra) and vice versa
