DESCRIPTION - summary of the module content

Complex analysis is one of the most beautiful and complete theories in mathematics.  Invented in the 19th century by Gauss, Cauchy and Riemann, it has developed into a powerful tool, indispensable to all mathematicians, pure and applied. The skill of computing integrals by means of residue calculus is a major tool in integration and it is an invaluable tool in physics and engineering. In this module, you will see the theory developed in a logical way, emphasizing the wide range of useful applications. You will learn to develop complex analysis in a logical and satisfying way that provides insight into the geometric and topological foundations of the subject. This skill is useful to engineers as it helps you to understand that taking a different viewpoint may render a difficult problem easy.
 

Prerequisite module: ECM2701 or equivalent
 

AIMS - intentions of the module

The main aim of this module is to inspire a genuine engagement with complex analysis and its applications in other branches of mathematics

RE-ASSESSMENT NOTES

If a module is normally assessed entirely by coursework, all referred/deferred assessments will normally be by assignment.


If a module is normally assessed by examination or examination plus coursework, referred and deferred assessment will normally be by examination. For referrals, only the examination will count, a mark of 40% being awarded if the examination is passed. For deferrals, candidates will be awarded the higher of the deferred examination mark or the deferred examination mark combined with the original coursework mark.
