MASSACHUSETTS INSTITUTE OF TECHNOLOGYDepartment of PhysicsString Theory (8.821) – Prof. J. McGreevy – Fall 2008End-of-Term ProjectDue: Topic choices are due Monday, November 10, 2008. Papers are due on theday of the last lecture.The end of term project for 8.821 will be a half-hour presentation or short (say5 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 tostudy 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 fromhaving to read the papers. Give some context, say what the crucial point is, saywhat the implications are.If you are planning to give a talk, I can’t recommend highly enough the advicefrom Geroch, gr-qc/9703019.Please tell me (by email or in person) what topic you plan to study as soonas possible; also tell me whether you wish to give a talk or write a paper. Beloware some topic suggestions, involving wildly varying levels of difficulty. The list iscertainly not in any sense exhaustive. Creative topics are encouraged.Some topic suggestions:Lists of references below are intended as entry points to the literature, and notas complete citations of all good work on the subject. For each paper you should ofcourse always also read all papers which cite it1, as well as all of the papers to whichit refers. The order below is not meaningful, though I’ve tried to group related topicstogether. I will keep adding to this file.1.
