Maxwell kinematical algebras and 3D gravities
Patrick Concha, Nelson Gallegos, Evelyn RodrÃguez +1
In this paper, we present a Maxwell extension of kinematical Lie algebras by promoting the contraction method underlying the Bacry and Lévy-Leblond cube to a semigroup expansion f…

3D Carrollian gravity from 2D Euclidean symmetry
Patrick Concha, Evelyn RodrÃguez, Sebastián Salgado
Carroll symmetry arises from Poincaré symmetry when the speed of light is sent to zero. In this work, we apply the Lie algebra expansion method to find the Carroll versions of dif…

Three-dimensional non-relativistic Hietarinta supergravity
Patrick Concha, Evelyn RodrÃguez, Sebastián Salgado
In this work we present the non-relativistic regime of the Hietarinta gravity theory and its extension to supergravity. At the bosonic level, we derive the non-relativistic version…
