Non-relativistic and Carrollian limits of Jackiw-Teitelboim gravity

A bstract We construct the non-relativistic and Carrollian versions of Jackiw-Teitelboim gravity. In second order formulation, there are no divergences in limits. Instead, first formalism, some can be avoided by starting from a relativistic BF theory with (A)dS 2 × ? gauge algebra. show how to define boundary duals gravity actions using method non-linear realisations suitable Inverse Higgs constraints. particular, version Schwarzian action is constructed this way. derive asymptotic symmetries theory, as well corresponding conserved charges Newton-Cartan geometric structure. Finally, we same construction applies case.
