- Topological spaces

Synergies: The following modules go well together with Introduction to Topology:
Leads to: The following modules have this module listed as assumed knowledge or useful background:
- MA3H6 Algebraic Topology
- MA475 Riemann Surfaces
- MA4H4 Geometric Group Theory
- MA4J7 Cohomology and Poincare Duality
Content: Topology is the study of properties of spaces invariant under continuous deformation. For this reason it is often called "rubber-sheet geometry''. The module covers: topological spaces and basic examples, compactness, connectedness and path-connectedness, identification topology, Cartesian products, homotopy and the fundamental group, winding numbers and applications, an outline of the classification of surfaces.
Aims: To introduce and illustrate the main ideas and problems of topology.
- To explain how to distinguish spaces by means of simple topological invariants (compactness, connectedness and the fundamental group)
- To explain how to construct spaces by gluing and to prove that in certain cases that the result is homeomorphic to a standard space
- To construct simple examples of spaces with given properties (e.g. compact but not connected or connected but not path connected).
