Course Overview

MATH2400 has several applications to algebraic coding, so is useful to students of computer science and communication theory. 

Starting from the Euclidean algorithm, we discuss continued fractions and congruences, and consider applications to the construction of secret codes in current use in commerce and industry. These techniques are then extended to polynomials, permitting the construction of the finite fields which are widely used in "error correcting codes'' which enable a digitised message to be restored after distortion due to "noise''.
