MA448 Hyperbolic Geometry

Not Running 2020/21


Term(s): Term 2

Status for Mathematics students: List C

Commitment: 30 Lectures

Assessment: 3-hour examination, 100%.

Prerequisites: MA225 Differentiation and MA3F1 Introduction to Topology. MA3B8 Complex Analysis strongly recommended. Closely related to Geometric Group Theory MA4H4, MA475 Riemann surfaces, MA455 Manifolds

Leads To:

Content: An introduction to hyperbolic geometry, mainly in dimension two, with emphasis on concrete geometrical examples and how to calculate them. Topics include: basic models of hyperbolic space; linear fractional transformations and isometries; discrete groups of isometries (Fuchsian groups); tesselations; generators, relations and Poincaré's theorem on fundamental polygons; hyperbolic structures on surfaces.

Aims: To introduce the beautiful interplay between geometry, algebra and analysis which is involved in a detailed study of the Poincaré model of two-dimensional hyperbolic geometry.

Objectives: To understand

  • the non-Euclidean geometry of hyperbolic space.
  • tesselations and groups of symmetries of hyperbolic space.
  • hyperbolic geometry on surfaces.
