CODE NO: MATH281 : TITLE: COMPLEX FUNCTIONS YEAR: 2 SEMESTER: 1 7.5 CREDITS DIVISION: Applied Mathematics STUDENT CONTACT: 24 hours (max) DELIVERY: 18 lectures and 6 tutorials PRE-REQUISITES: MATH101-3 CO-REQUISITES: None BARRED COMBINATIONS: None FOLLOW-UP MODULES: Any Honours module on Complex Analysis or Complex Dynamics.Certain Physics modules. PRELIMINARY READING: Revision of any previous work on complex numbers, with emphasis on the role of the module circle. AIMS: To introduce the student to a surprising, very beautiful theory having intimate connections with other areas of mathematics and physical sciences, for instance ordinary and partial differential equations and potential theory. LEARNING OUTCOMES: After completing this module students should: * appreciate the central role of complex numbers in mathematics; * be competent at computing contour integrals and Green theorem. * be able to compute Taylor and Laurent series of such functions; * understand the content and relevance of the various Cauchy formulae and theorems; * be familiar with the reduction of real definite integrals to contour integrals. OUTLINE SYLLABUS: Reminder of complex arithmetic. Cauchy-Riemann equations. Green theorems. Contour integration and Cauchys Theorem. Taylor and Laurent Series Poles and essential singularities. The Residue Theorem. Evaluation of real integrals by means of contour integration.
