Routh Reduction of Palatini Gravity in Vacuum

An interpretation of Einstein-Hilbert gravity equations as a Lagrangian reduction of Palatini gravity is made. The main technique involved in this task consists of representing the equations of motion as a set of differential forms on a suitable bundle. In this setting, Einstein-Hilbert gravity can...

An interpretation of Einstein-Hilbert gravity equations as a Lagrangian reduction of Palatini gravity is made. The main technique involved in this task consists of representing the equations of motion as a set of differential forms on a suitable bundle. In this setting, Einstein-Hilbert gravity can be considered as a kind of Routh reduction of the underlying field theory for Palatini gravity. As a byproduct of this approach, a novel set of conditions for the existence of a vielbein for a given metric is found.
The author thanks the CONICET and UNS for financial support, and Eduardo Garca-Torano for valuable discussion regarding aspects of Routh reduction contained in this article, as well as for pointing me out to reference [28]. Also, the author would like to warmly thank the referees for the care they put into reviewing this work. The article has been greatly improved by their suggestions.
