Semi-simple enlargement of the algebra from a Chern-Simons theory
Patrick Concha, Nelson Merino, Evelyn Rodríguez +2
In this work we present a BMS-like ansatz for a Chern-Simons theory based on the semi-simple enlargement of the Poincaré symmetry, also known as AdS-Lorentz algebra. We start by sh…
Asymptotic symmetries of three-dimensional Chern-Simons gravity for the Maxwell algebra
Patrick Concha, Nelson Merino, Olivera Miskovic +3
We study a three-dimensional Chern-Simons gravity theory based on the Maxwell algebra. We find that the boundary dynamics is described by an enlargement and deformation of the $\ma…
Chern-Weil theorem, Lovelock Lagrangians in critical dimensions and boundary terms in gravity actions
Nathalie Deruelle, Nelson Merino, Rodrigo Olea
In this paper we show how to translate into tensorial language the Chern-Weil theorem for the Lorentz symmetry, which equates the difference of the Euler densities of two manifolds…
On the algorithm to find S-related Lie algebras
Carlos Inostroza, Igor Kondrashuk, Nelson Merino +1
In this article we describe the Java library that we have recently constructed to automatize the S-expansion method, a powerful mathematical technique allowing to relate different…
On a Java library to perform S-expansions of Lie algebras
Carlos Inostroza, Igor Kondrashuk, Nelson Merino +1
The S-expansion method is a generalization of the Inönü-Wigner (IW) contraction that allows to study new non-trivial relations between different Lie algebras. Basically, this metho…
