A Ponzano-Regge model of Lorentzian 3-Dimensional gravity
Laurent Freidel
文献摘要
We present the construction of the partition function of 3-dimensional gravity in the Lorentzian regime as a state sum model over a triangulation. This generalize the work of Ponzano and Regge to the case of Lorentzian signature.
