Maxwell kinematical algebras and 3D gravities
Patrick Concha, Nelson Gallegos, Evelyn Rodríguez +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 fr…
3D Carrollian gravity from 2D Euclidean symmetry
Patrick Concha, Evelyn Rodríguez, 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 diff…
Three-dimensional non-relativistic Hietarinta supergravity
Patrick Concha, Evelyn Rodríguez, 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…
Four dimensional topological supergravities from transgression field theory
Patrick Concha, Fernando Izaurieta, Evelyn Rodríguez +1
In this work, we propose a four-dimensional gauged Wess-Zumino-Witten model, obtained as a dimensional reduction from a transgression field theory invariant under the $\mathcal{N}=…
