Unit aims
The aims of this unit are to enable students to gain an understanding and appreciation of algebraic number theory and familiarity with the basic objects of study, namely number fields and their rings of integers. In particular, it should enable them to become comfortable working with the basic algebraic concepts involved, to appreciate the failure of unique factorisation in general, and to see applications of the theory to Diophantine equations.
General Description of the Unit
Algebraic Number Theory is a major branch of Number Theory (alongside Analytic Number Theory) which studies the algebraic properties of algebraic numbers – in particular the factorization of algebraic integers and ideals – in a setting in which familiar features of the (usual) integers, such as unique factorization, need not hold. The unit will provide an introduction to algebraic number theory, focussing on algebraic number fields and their rings of integers, ideals and factorization, units and the ideal class group, and will explore some applications to Diophantine equations.
In addition, students will have the opportunity to develop an awareness of a broader literature and gain an appreciation of how the basic ideas may be further developed through an individual project.
Relation to Other Units
The course build on the material of Algebra 2 (Math 21800) and has relations to Galois Theory (Math M2700). The material is complementary to that of Analytic Number Theory (Math M0007).

Learning Objectives
Students who successfully complete the unit should be able to:
By pursuing an individual project on a more advanced topic students should have:
Transferable Skills
Using an abstract framework to better understand how to attack a concrete problem.
Lectures, including examples and revision classes, supported by lecture notes with problem sets and model solutions. Self-study with directed reading based on recommended material.
80% Examination and 20% Coursework.
Raw scores on the examinations will be determined according to the marking scheme written on the examination paper. The marking scheme, indicating the maximum score per question, is a guide to the relative weighting of the questions. Raw scores are moderated as described in the Undergraduate Handbook.
Lecture notes and handouts will be provided covering all the main material.
The following supplementary texts provide additional background reading:
