Rings, fields, ideals, algebraic extension fields. Coding theory and cryptographic applications of finite fields. Gaussian integers, Hamilton's quaternions, Chinese Remainder Theorem. Euclidean Algorithm in further fields.


On completion of this unit students will be able to:

  1. Appreciate advanced concepts, algorithms and results in number theory;

  1. Use Gaussian integers to find the primes expressible as a sum of squares;

  1. Understand Diophantine equations, primitive roots and the quaternions - the best known skew field;

  1. Appreciate many of the links between algebra and number theory;

  1. Understand the most commonly occurring rings and fields: integers, integers modulo n, rationals, reals and complex numbers, more general structures such as algebraic number fields, algebraic integers and finite fields;

  1. Perform calculations in the algebra of polynomials;

  1. Use the Euclidean algorithm in structures other than integers;

  1. Construct larger fields from smaller fields (field extensions);

  1. Apply field theory to coding and cryptography.
