Department: Mathematical Sciences

MATH3201: GEOMETRY III

Type Open Level 3 Credits 20 Availability Available in 2021/22 Module Cap Location Durham

Prerequisites

  • Complex Analysis II (MATH2011) AND Analysis in Many Variables II (MATH2031) AND Algebra II (MATH2581).

Corequisites

  • None.

Excluded Combination of Modules

  • None.

Aims

  • To give students a basic grounding in various aspects of plane geometry.
  • In particular, to elucidate different types of plane geometries and to show how these may be handled from a group theoretic viewpoint.

Content

  • Euclidean geometry: isometry group, its generators, conjugacy classes.
  • Discrete group actions: fundamental domains, orbit space.
  • Spherical geometry.
  • Affine geometry.
  • Projective line and projective plane. Projective duality.
  • Hyperbolic geometry: Klein disc model (distance, isometries, perpendicular lines).
  • Moebius transformations, inversion, cross-ratios.
  • Inversion in space and stereographic projection.
  • Conformal models of hyperbolic geometry (Poincare disc and upper half-plane models).
  • Elementary hyperbolic geometry: sine and cosine rules, area of a triangle.
  • Projective models of hyperbolic geometry: Klein model and hyperboloid model.
  • Types of isometries of the hyperbolic plane. Horocycles and equidistant curves.
  • Additional topics: hyperbolic surfaces, 3D hyperbolic geometry.

Learning Outcomes

Subject-specific Knowledge:
  • By the end of the module students will: be able to solve novel and/or complex problems in Geometry.
  • have a systematic and coherent understanding of theoretical mathematics in the field of Geometry.
  • have acquired a coherent body of knowledge of these subjects demonstrated through one or more of the following topic areas: Isometries and affine transformations of the plane.
  • Spherical geometry.
  • Mobius transformations.
  • Projective geometry.
  • Hyperbolic geometry.
Subject-specific Skills:
  • In addition students will have specialised mathematical skills in the following areas which can be used with minimal guidance: Spatial awareness.
Key Skills:

    Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

    • Lectures demonstrate what is required to be learned and the application of the theory to practical examples.
    • Assignments for self-study develop problem-solving skills and enable students to test and develop their knowledge and understanding.
    • Formatively assessed assignments provide practice in the application of logic and high level of rigour as well as feedback for the students and the lecturer on students' progress.
    • The end-of-year examination assesses the knowledge acquired and the ability to solve unpredictable problems of some complexity.
