Course Description: |
This course is concerned with the study of topological spaces and their structure preserving maps (continuous maps). Topological methods and ideas are universal in modern mathematics. A topological space is a type of geometric object that does not necessarily have a distance function associated with it but, via the notion of open sets (introduced by axiomatic properties), it encodes the rigorous approach to the idea of "continuity" and "nearness". Many different examples of topological spaces will be examined, including a class of topological spaces called topological manifolds (spaces that locally look like a Euclidean space), and in particular 2-dimensional topological manifolds, called "surfaces". Examples of surfaces are the sphere, R2, torus, Klein bottle. The course concludes with an introduction to combinatorial topology (which considers topological spaces by means of simplicial complexes and triangulations). We discuss the classification theorem for closed surfaces. |
