MATH4AR Advanced Topics in General Relativity
General relativity (GR), Albert Einstein’s theory of gravitation, is one of the most elegant theories of mathematical physics. It gives a geometric description of gravitation in terms of the curvature of space and time, using mathematical methods like tensor algebra, differential geometry and the theory of ordinary and partial differential equations. GR is also one of the best verified theories of modern physics. In particular, it is regarded as the most satisfactory model of the large-scale universe that we have.
This course builds upon the previous modules Introduction to General Relativity (MATH4GR) and Differential Geometry (MATH4DG), where the mathematical prerequisites have been supplied. It consists of a selection of fundamental topics in GR, including discussions of black holes and of simple models for neutron stars, which are among the most extreme objects in our universe.
Further topics are cosmological models and gravitational waves.
The introduction to cosmological models will focus on the so-called Friedmann models, describing a homogeneous and isotropic universe. These models are mathematically relatively simple, but indicate already that our universe could have arisen from a big bang. Gravitational waves are little ripples propagating through spacetime, which can result from the asymmetric acceleration of mass during massive astronomical events. They are a major topic of current research and their (still outstanding) direct observation would provide a “new window to the universe”.

3 written assignments, 1 presentation
Your final mark F in the paper will be calculated according to this formula:
F = 0.5A + 0.5P
- A is the Assignments mark
- P is the Presentation mark
and all quantities are expressed as percentages.
Students must abide by the University’s Academic Integrity Policy
Academic endeavours at the University of Otago are built upon an essential commitment to academic integrity.
The two most common forms of academic misconduct are plagiarism and unauthorised collaboration.
Academic misconduct: Plagiarism
Plagiarism is defined as:
- Copying or paraphrasing another person’s work and presenting it as your own.
- Being party to someone else’s plagiarism by letting them copy your work or helping them to copy the work of someone else without acknowledgement.
- Using your own work in another situation, such as for the assessment of a different paper or program, without indicating the source.
- Plagiarism can be unintentional or intentional. Even if it is unintentional, it is still considered to be plagiarism.
All students have a responsibility to be aware of acceptable academic practice in relation to the use of material prepared by others and are expected to take all steps reasonably necessary to ensure no breach of acceptable academic practice occurs. You should also be aware that plagiarism is easy to detect and the University has policies in place to deal with it.
Academic misconduct: Unauthorised Collaboration
Unauthorised Collaboration occurs when you work with, or share work with, others on an assessment which is designed as a task for individuals and in which individual answers are required. This form does not include assessment tasks where students are required or permitted to present their results as collaborative work. Nor does it preclude collaborative effort in research or study for assignments, tests or examinations; but unless it is explicitly stated otherwise, each student’s answers should be in their own words. If you are not sure if collaboration is allowed, check with your lecturer.
