## Module content and teaching

###### Principal aims

To demonstrate that uniqueness of factorization into irreducibles can fail in rings of algebraic integers, but that it can be replaced by the uniqueness of factorization into prime ideals.To introduce some geometric lattice-theoretic techniques and their applications to algebraic number theory.

###### Principal learning outcomes

By the end of the course students will: be able to compute norms and discriminants and to use them to determine the integer rings in algabraic number fields; be able to factorize ideals into prime ideals in algebraic number fields in straightforward examples; understand the proof of Minkowski's Theorem on lattices, and be able to apply it, for example, to prove that all positive integers are the sum of four squares.
