Introduction Module outline and schedule

Module outline and scheduleThis is a first course on the theory of functions of one complex variable. Aswell as being a rich and beautiful theory in its own right, it has innumerableapplications in physics, engineering and other areas of mathematics.

Topics coveredComplex numbers, functions defined on the complex plane, complex dif-ferentiability and the Cauchy-Riemann equations.Integration along paths in the complex plane, Cauchy’s Theorem andCauchy’s Integral Formula.Power series, Taylor’s Theorem, Liouville’s Theorem, the FundamentalTheorem of Algebra and the Identity Theorem.Laurent’s Theorem, singularities, Cauchy’s Residue Theorem.Applications of the residue calculus to contour integration.
