Talk:Jackiw–Teitelboim gravity

Something missing to lagrangian?
Please correct me if I am wrong but I think there is something missing to the free part of the Lagrangian inside the action namely an additional term $$ \frac{1}{2} g^{\mu\nu}\partial_\mu \Phi \partial_\nu \Phi $$? TonyMath (talk) 05:43, 4 April 2012 (UTC)


 * Wish someone provided an answer. That Lagrangian is more than wrong:  the matter part should not by multiplied by $$ \Phi $$: you are simply getting the Einstein-Hilbert action with an additional matter contribution all multiplied by $$ \Phi $$ i.e. equivalent to a conformal transformation!  This has to be fixed.  The papers by Mann an co-workers provide the correct action.  TonyMath (talk) 19:23, 2 June 2012 (UTC)


 * No response. If nobody has any objections, then I would like to make the fix myself. TonyMath (talk) 16:58, 7 June 2012 (UTC)


 * I added the changes using the paper by Mann and co-workers as my model. TonyMath (talk) 01:05, 11 June 2012 (UTC)
