We explain the method and illustrate its applications by giving several explicit examples. The method can be generalized to include ultra-relativistic gravity and non-relativistic supergravity as well. application/pdf eng Springer info:eu-repo/semantics/openAccess https://creativecommons.org/licenses/by/4.0/ Atribución 4.0 Internacional Classical Theories of Gravity Space-Time Symmetries Chern-Simons Theories Effective Field Theories Lie algebra expansions and actions for non-relativistic gravity info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://link.springer.com/article/10.1007/JHEP08(2019)048 SI
