Graduate Deriving Field Equations of Einstein-Cartan Theory from Hilbert Action
Well, see I am totally unaware and uninterested in all that. Maybe you should relax and bring up such things only when people are acutally talking about it. From the abstract you linked, that "theory" used Einstein-Cartan geometry and that is the only link to this thread. Our questions were...- zorgkang

Graduate Deriving Field Equations of Einstein-Cartan Theory from Hilbert Action
Thanks, well yes I've been reading here and there all afternoon. Read some stuff on wikipedia, a few articles, forum posts, looked in standard GR books, etc. But what I really need is a book or review article or something like that. I suppose I should also say I'm looking for 2 things: 1...- zorgkang

Graduate Deriving Field Equations of Einstein-Cartan Theory from Hilbert Action
Hehe, interesting response. I don't really see why though. As I understand it, Einstein-Cartan is just the extension of GR allowing for non-zero torsion and is derived from the same Hilbert-Einstein action, but taking the connection instead of the metric as dynamical variables. (might be...- zorgkang

I was going to post almost the exact same question. Maybe a bit easier, where can I find a good introduction to the tetrad formalism? Hopefully including the information asked for above. Cheers- zorgkang
