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)
