Generalized cosmological term from Maxwell symmetries

Abstract: By gauging the Maxwell spacetime algebra the standard geometric framework of Einstein gravity with cosmological constant term is extended by adding six fourvector fields A_\mu^{ab}(x) associated with the six abelian tensorial charges in the Maxwell algebra. In the simplest Maxwell extension of Einstein gravity this leads to a generalized cosmological term that includes a contribution from these vector fields. We also consider going beyond the basic gravitational model by means of bilinear actions for the new A… Show more

“…Soroka [25] presented another approach to the problem but this time gauging semi-simple extension of Poincare algebra. The formulation of different types of Maxwell gravities has already been done in [26][27][28]. With this motivation, we have presented the gauge theory of Maxwell-Weyl group denoted by MW (1, 3).…”

“…The second term in the rhs of (23) provides a field-dependent modification of the cosmological constant at the lhs of the equation. We wish to add that: 1) Using equations (15) and (16), the spin connection may be expressed as a function ω ab (e, A) of the vierbein and the new gauge fields (for perturbative solutions see [6], Appendix). In such a way we obtain the second order formulation of Maxwell gravity, with independent fields e a µ and A ab µ .…”
