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...

| description | 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. en Інститут математики НАН України Symmetry, Integrability and Geometry: Methods and Applications Routh Reduction of Palatini Gravity in Vacuum Article published earlier |
