Module summary

Riemann surfaces lie at the interface of complex analysis, complex geometry and algebraic geometry. This course provides an introduction to Riemann surfaces, from the initial concepts through to more advanced applications. The course will emphasise concrete examples of algebraic curves to help visualise the theoretical concepts.

Additional information

A course in complex analysis that covers holomorphic and meromorphic functions, Laurent series, complex integration and Cauchy’s theorem will give sufficient background for this course. It is expected that students have sound knowledge of all of these topics before the course begins.

Some of the concepts used in this course will be introduced at a fast pace, therefore it will be useful to have seen the topics below.

  • Charts and Atlases (such as those studied in Differential Geometry of Curves and Surfaces)

  • Distinguishing compact surfaces by their genus (studied in Topology)

Module aims

Riemann surfaces lie at the interface of complex analysis, complex geometry and algebraic geometry. This course provides an introduction to Riemann surfaces, from the initial concepts through to more advanced applications. The course will emphasise concrete examples of algebraic curves to help visualise the theoretical concepts.

Module learning outcomes

By the end of the course, students will be able to

  1. Use charts and atlases to prove that a given system of equations defines a Riemann surface.

  2. Construct examples of Riemann surfaces as algebraic curves and compute their genus.

  3. Integrate a differential form on a Riemann surface.

  4. Use the long exact sequence to compute sheaf cohomology groups.

  5. Use the Riemann-Roch theorem to compute sheaf cohomology groups.

Additional assessment information

  • Four homework sets (5% each) which are separate from (but related to) the associated seminar (first four seminars). Extensions are possible, as solutions won’t be released until all the marking is complete. [The fifth seminar will have a formative assignment associated with it].

  • Final exam (80%).
