Inönü-Wigner Contraction and Supergravity
P. K. Concha, O. Fierro, E. K. Rodríguez
We present a generalization of the standard Inönü-Wigner contraction by rescaling not only the generators of a Lie superalgebra but also the arbitrary constants appearing in the co…
On the Supersymmetric Extension of Gauss-Bonnet like Gravity
P. K. Concha, M. C. Ipinza, L. Ravera +1
We explore the supersymmetry invariance of a supergravity theory in the presence of a non-trivial boundary. The explicit construction of a bulk Lagrangian based on an enlarged supe…
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…
Pure Lovelock gravity and Chern-Simons theory
P. K. Concha, R. Durka, C. Inostroza +2
We explore the possibility of finding Pure Lovelock gravity as a particular limit of a Chern-Simons action for a specific expansion of the AdS algebra in odd dimensions. We derive…
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…
