Non-Relativistic Chern-Simons Supergravity with Torsion
Francisco Barriga, Patrick Concha, Nelson Merino +1
In this work, we construct a three-dimensional non-relativistic Chern--Simons supergravity theory with both curvature and torsion within the Mielke--Baekler framework. We show that…
Torsional Carroll Gravity
P. Concha, N. Merino, L. Ravera +1
The ultra-relativistic (Carrollian) regime of gravity has recently emerged as a fertile framework for exploring holography, non-Lorentzian symmetries, and geometric limit of Genera…
Inhomogeneous metrics on complex bundles in Lovelock gravity
Cristóbal Corral, Borja Diez, Daniel Flores-Alfonso +2
We consider Lovelock gravity in arbitrary, even dimensions. We find a large class of new gravitational instantons by considering extended nontrivial circle bundles over Kähler mani…
Non-relativistic limit of the Mielke-Baekler gravity theory
Patrick Concha, Nelson Merino, Evelyn Rodríguez
In this paper, we present the most general non-relativistic Chern-Simons gravity model in three spacetime dimensions. We first study the non-relativistic limit of the Mielke-Baekle…
Lovelock gravities from Born-Infeld gravity theory
P. K. Concha, N. Merino, E. K. Rodríguez
We present a Born-Infeld gravity theory based on generalizations of Maxwell symmetries denoted as . We analyze different configuration limits allowing to recover…
New family of Maxwell like algebras
P. K. Concha, R. Durka, N. Merino +1
We introduce an alternative way of closing Maxwell like algebras. We show, through a suitable change of basis, that resulting algebras are given by the direct sums of the AdS and t…
General properties of the expansion methods of Lie algebras
Laura Andrianopoli, Nelson Merino, Felip Nadal +1
The study of the relation between Lie algebras and groups, and especially the derivation of new algebras from them, is a problem of great interest in mathematics and physics, becau…
