Course aims

Since the introduction of digital computers, the importance of discrete and thus finite problems in mathematics has become apparent. For this reason this course, which introduces students to some basic ideas on Finite Mathematics, should prove useful to future Computer Scientists and Software Engineers while at the same time providing Mathematics students with an introduction to ideas in Number Theory, the theory of finite fields, cryptography and Algebraic Coding Theory. There is a follow-on course, MATH3411, Information, Codes and Ciphers, which develops the ideas in greater depth.

Course description

This is an introduction to those areas of Mathematics which underpin parts of computing. The main topics are integer and modulo arithmetic (including tests for primeness of integers), polynomial algebra (including factorization of polynomials and creation of new fields) and an introduction to cryptography and error correcting codes.

Note: MATH1081 Discrete Mathematics is recommended.
