Could you suggest a good survey paper on positive mass theorem?

3$\begingroup$ Come to think of it, "good" is subjective. What are your backgrounds and what are you looking for in one such survey? (In particular, why not read the original papers?) $\endgroup$ – Willie Wong Jun 16 '11 at 16:04

H. Bray's articles "Black Holes, Geometric Flows, and the Penrose Inequality in General Relativity" (Notices AMS, 2002) contains a very short, but elegant, survey of the positive mass theorem. He also has a longer survey that goes into several simpler cases.

1$\begingroup$ This survey says only whodidandwhat but it does not discuss the ideas in the proof. It also does not mention many related results. $\endgroup$ – εδ Jun 20 '11 at 13:52
Maybe Markus Khuri's RTG notes would help?
There's also a set of lecture notes by Rick Schoen for his 2009 course in Stanford on General Relativity, which has a nice discussion of the fundamental ideas involved in the proof of the PMT. I don't know if it is publich available on the internet though...
