Summary  Core course for Honours Degrees involving Mathematics.
This is a first course in complex analysis. Topics are: Analytic functions, Moebius transformations and the Riemann sphere, complex integration, series expansions, the residue calculus and its applications.
In the 'skills' section of this course we will work on Mathematical reading and writing, although the skills involved are widely applicable to reading and writing technical and nontechnical reports. Students will then use these skills complete a group project re searching a topic connected with complex numbers or complex analysis and produce a written report. 
Course description 
Holomorphic functions: complex numbers, algebraic, geometric and topological properties of the complex plane, functions of a complex variable, differentiability and holomorphicity, CauchyRiemann equations, harmonic functions. Examples: polynomials, rational functions, exponential and related functions. Multivalued functions: the logarithm and complex powers, branches and an example of a Riemann surface.
Holomorphic functions as mappings: Moebius transformations, the extended complex plane and the Riemann sphere, the crossratio. How to visualise functions of a complex variable.
Complex integration: contour integrals, independence of path, the Cauchy Integral Theorem, the Cauchy Integral Formulae, Morera's Theorem, Lioville's Theorem and its applications, the Maximum modulus principle.
Series expansions: holomorphic functions as analytic functions, Taylor and Laurent series, zeros, singularities, analytic continuation.
Residue theory: the Cauchy Residue Theorem, the argument principle, Rouche's Theorem and applications to the evaluation of real integrals and of sums.
Skills: The content will be chosen appropriate to the learning outcomes.

Learning Outcomes
On completion of this course, the student will be able to:
 Calculate proficiently with complex numbers, including solving algebraic equations.
 Understand the notion of holomorphicity/analyticity in its many manifestations and ability to use their basic properties with confidence.
 Be familiar with elementary holomorphic functions, including multivalued functions, and the ability to work with them effectively.
 Apply the basic integral theorems to the evaluation of sums and integrals and to the determination of number of poles and zeros of meromorphic functions.
 Expand meromorphic functions (especially rational functions) in series and to deduce information about their singularities.
