In another thread, about something else (dynamical triangulations approach to quantizing Gen Rel) Severian pointed to this new posting as "a more interesting paper about gravity"

 

"Lagrangian formalism of gravity in the Randall-Sundrum model"

http://www.arxiv.org/abs/hep-ph/0412109

 

Could be worth checking out. Anyone have comments?

Want to say why it could be of special interest?

Sorry I have not gotten back to this. Incredibly busy at the moment....

 

Will go read the paper sometime soon...

no problem!

I haven't read it either. Glad to hear they are keeping you busy.

You mentioned you might be teaching Feynman path integral next

term IIRC. You may well getting ready for that among other stuff.

 

I made a separate thread for this because I didnt want the link and

the paper you thought interesting to get lost, and it didnt fit into the

dynamical triangulation (DT) context. I looked at it and decided it was

out of bounds for me, but others may be interested as you were.

 

right now the only new approach to gravity I know of making real progress, is DT----anyway that is my impression among those that are fundamental and not merely effective theories. you may have a different view...
