Description

This module provides students with the mathematical tools required to study General Relativity (GR), and introduces them to the area. The module includes the study of the conceptual foundations of GR and Einstein's equation, the study of the Schwarzschild solution, and the analysis of the classical tests of GR.

Learning Outcomes

1. Complete a range of calculations relevant to the mathematics of curved space-time (tensor algebra, metrics, connections, curvature, geodesics, isometries).
2. Use computer algebra to carry out a range of calculations relevant to the mathematics of curved space-time.
3. Solve a range of problems relating to the mathematics of curved space-time.
4. Apply their knowledge of differential geometry to describe and analyse different phenomena of gravitational fields.
5. Apply their knowledge of differential geometry to solve a range of problems relating to gravitational fields.
6. Analyse the conceptual foundations of General Relativity and discuss how these limit possible theories of gravitation.
7. Compare and contrast General Relativity with other theories of gravitation, both conceptually and in terms of observational evidence.
