Go to amazon.co.uk and do a search for: Quantum Gravity & Gravitational Waves: " Ripples in The Curvature of Space-Time " Paperback – 7 Dec 2015 by Edited by Paul F. Kisak (Author) Look inside the book on the chapter on loop quantum gravity. The guy has taken the wikipedia page on LQG and just pasted it into his book. The thing is I wrote most of that wikipedia page. (user name "Ibayn"). The wiki page is incomplete, probably mistakes, parts need more clarification (and it covers mostly canonical LQG, not so much covariant LQG). But now I dont want to edit the wiki page if somebody is just going to put it in their book and make money off it. I've written 178 pages of notes on covariant loop quantum gravity and was planning on putting together a new wikipedia page Called "Covariant loop quantum gravity" as well at some point but maybe not now. I've been writing numerous notes on GR and LQG (where write up details of calculations) some of which I might want to self publish as books myself - I've already put up some of the notes on wiki, I've wanted to put up more but what if somebody takes what I put up, paste it into a book, and calls it copyright material? I've written up all of/a lot of the material in the wiki pages "Hamiltonian constraint of LQG" - I'm missing stuff on matter coupling there and inclusion of their qunatization. "Tetradic Palantini action" "Self-dual Palatini action" - important proofs of stuff I could not find in any text and only came across in some quasi-paper, I have written up on wiki and checked it is correct. I've included the derivation of Ashtekar's formalism from the Self-dual action. "Ashtekar variables" page. "Quantum configuration space".
