8.821 | Fall 2008 | Graduate

String Theory


The end of term project for 8.821 will be a half-hour presentation or short (say 5 pages) paper summarizing a topic of interest, relevant to our class. The topic needn’t be about string theory or gauge/gravity duality specifically.

An appropriate topic could also be a system that you think may be amenable to study with a gravity dual and want to learn more about.

Your goal in deciding what to say should be to try to save the rest of us from having to read the papers. Give some context, say what the crucial point is, say what the implications are.

If you are planning to give a talk, I can’t recommend highly enough the advice from Geroch, gr-qc/9703019.

Below are some topic suggestions, involving wildly varying levels of difficulty. The list is certainly not in any sense exhaustive. Creative topics are encouraged.

Some Topic Suggestions
