Carroll versus Galilei from a Brane Perspective
Eric Bergshoeff, José Manuel Izquierdo, Luca Romano
We show that our previous work on Galilei and Carroll gravity, apt for particles, can be generalized to Galilei and Carroll gravity theories adapted to p-branes (p = 0, 1, 2, ...).…
Lie Algebra Expansions and Actions for Non-Relativistic Gravity
Eric Bergshoeff, Jose Manuel Izquierdo, Tomas Ortin +1
We show that the general method of Lie algebra expansions can be applied to re-construct several algebras and related actions for non-relativistic gravity that have occurred in the…
Extended Bargmann supergravity from a Lie algebra expansion
José A. de Azcárraga, Diego Gútiez, José M. Izquierdo
In this paper we show how the method of Lie algebra expansions may be used to obtain, in a simple way, both the extended Bargmann Lie superalgebra and the Chern-Simons action assoc…
Bosonic D=11 supergravity from a generalized Chern-Simons action
D. Camarero, J. A. de Azcarraga, J. M. Izquierdo
It is shown that the action of the bosonic sector of D=11 supergravity may be obtained by means of a suitable scaling of the originally dimensionless fields of a generalized Chern-…
Two-twistor particle models and free massive higher spin fields
J. A. de Azcarraga, S. Fedoruk, J. M. Izquierdo +1
We present D=3 and D=4 models for massive particles moving in a new type of enlarged spacetime, with D-1 additional vector coordinates, which after quantization lead to the towers…
Minimal D=4 supergravity from the superMaxwell algebra
J. A. de Azcarraga, J. M. Izquierdo
We show that the first-order D=4, N=1 pure supergravity lagrangian four-form can be obtained geometrically as a quadratic expression in the curvatures of the Maxwell superalgebra.…
