MATH6137 Homotopy and Homology

Module Overview

Homotopy theory is the study of continuous deformations. A geometric object may be continuously deformed by pulling, stretching, pressing or compressing, but not by tearing or puncturing (which are discontinuous). Two objects can then be regarded as equivalent if one can be continuously deformed into the other and vice-versa. The goal of homotopy theory is to determine which geometric objects are equivalent in this sense, or not. To do this, methods are needed which assign algebraic information to these geometric objects which are invariant (stay the same) under continuous deformations. Examples consider in the module are homotopy groups and homology groups.

Aims and Objectives

Module Aims

Description Students will gain an understanding of essential concepts in homotopy theory. They will be able to use logical and coherent arguments to prove basic results in homotopy theory and homology. They will be able to apply and test the theoretical results on a range of spaces, including spheres, real and complex projective spaces, and matrix groups. Students will be able to demonstrate a practical grasp of the material by being able to calculate an array of algebraic invariants involving homotopy groups; homotopy sets with group structure; homology groups.
