7. Other?

Husain and Winkler's paper is not a LQG paper but is interesting because it confirms Bojowald's loop quantum cosmology results using (pre-LQG) ADM variables and the Wheeler-deWitt equation. One can remove the Big Bang singularity using the canonical quantization of GR developed in the 1960s. In this case, Wheeler and deWitt's canonical quantization of the GR metric ("geometrodynamics") gives results similar to present loop cosmology.

Gambini and Pullin's is mainly just the most recent survey (a survey by Ashtekar and Lewandowski is in the works but not out yet).

The others on the menu are self-explanatory or ones we've discussed some at PF. Add your own favorites!

Which papers do you think show originality, break new ground in promising directions, achieve landmark results, may be cited in the future by lines of research starting from them, or are just plain interesting?
