Non-relativistic and Carrollian limits of Jackiw-Teitelboim gravity

Joaquim Gomis, Diego Hidalgo, Patricio Salgado-Rebolledo

We construct the non-relativistic and Carrollian versions of Jackiw-Teitelboim gravity. In the second order formulation, there are no divergences in the non-relativistic and Carrol…
