Chern-Simons and Born-Infeld gravity theories and Maxwell algebras type

preprint2014arXivOpen access

Abstract

Recently was shown that standard odd and even-dimensional General Relativity can be obtained from a (2n+1)(2n+1)-dimensional Chern-Simons Lagrangian invariant under the B2n+1B_{2n+1} algebra and from a (2n)(2n)-dimensional Born-Infeld Lagrangian invariant under a subalgebra LB2n+1\cal{L}^{B_{2n+1}} respectively. Very Recently, it was shown that the generalized Inönü-Wigner contraction of the generalized AdS-Maxwell algebras provides Maxwell algebras types Mm\cal{M}_{m} which correspond to the so called BmB_{m} Lie algebras. In this article we report on a simple model that suggests a mechanism by which standard odd-dimensional General Relativity may emerge as a weak coupling constant limit of a (2p+1)(2p+1)-dimensional Chern-Simons Lagrangian invariant under the Maxwell algebra type M2m+1\cal{M}_{2m+1}, if and only if m≥pm\geq p. Similarly, we show that standard even-dimensional General Relativity emerges as a weak coupling constant limit of a (2p)(2p)-dimensional Born-Infeld type Lagrangian invariant under a subalgebra LM2m\cal{L}^{\cal{M}_{2m}} of the Maxwell algebra type, if and only if m≥pm\geq p. It is shown that when m<pm<p this is not possible for a (2p+1)(2p+1)-dimensional Chern-Simons Lagrangian invariant under the M2m+1\cal{M}_{2m+1} and for a (2p)(2p)-dimensional Born-Infeld type Lagrangian invariant under LM2m\cal{L}^{\cal{M}_{2m}} algebra.
