The lecture courses.

The following is a preliminary outline of each course. Each course will include exercise sessions supervised by the lecturers, together with PhD students

The Compactness Theorem

Mike Prest (University of Manchester)

Lecture notes.

The word problem in combinatorial group and semigroup theory

Robert Gray (University of East Anglia)

Abstract and reading list.
Lecture notes.

Local-Global Principles in Number Theory

Shaun Stevens (University of East Anglia)

Background reading - if you are unfamiliar (or a bit rusty) with congruences, rings or groups, then please read up on them before the summer school. In partciular, make sure you are familiar with:
  • The Euclidean algorithm, modular arithmetic using numbers, including that a is invertible mod n iff gcd(a,n)=1.
  • The basic language of rings and fields, including units in a ring.
  • Modular arithmetic with the viewpoint of rings & fields: that Z/nZ is a ring, that its group of units is the classes of m coprime to n... so that Z/nZ is a field iff n is prime.
If you need to brush up on these things then the Oxford notes cover everything and more. The first year notes from UEA contain the bare minimum that you need to know before starting. If you have also read the Chinese Remainder Theorem, and seen that (Z/pZ)* is cyclic then so much the better.
