Jackiw–Teitelboim gravity : ウィキペディア英語版 | Jackiw–Teitelboim gravity The R=T model,〔 〕 also known as Jackiw–Teitelboim gravity is a theory of gravity with dilaton coupling in one spatial and one time dimension. It should not be confused〔 〕 with the CGHS model or Liouville gravity. The action is given by : denotes the covariant derivative and the equation of motion is : The metric in this case is more amenable to analytical solutions than the general 3+1D case. For example, in 1+1D, the metric for the case of two mutually interacting bodies can be solved exactly in terms of the Lambert W function, even with an additional electromagnetic field (see quantum gravity and references for details). == See also ==
