Module title:Number Theory
Module codeMTH3004
Module lecturers:Dr Henri Johnston
Module credits:15

Number theory is a vast and fascinating field of mathematics, consisting of the study of the properties of whole numbers. From this module, you will acquire a working knowledge of the main concepts of classical elementary number theory. This will be developed as a rigorous proof-based theory along with some appreciation of the theory behind modern computational techniques. Topics studied include divisibility properties of natural numbers, congruences, prime numbers, primality and factorisation, quadratic reciprocity, sums of squares and Fermat’s last theorem for the special case of sums of fourth powers.

Prerequisite module: MTH2002 or MTH2010 , or equivalent
