Symmetry reduction of gravitational Lagrangians

G Frausto, I Kolář, T Málek, C Torre - arXiv preprint arXiv:2410.11036, 2024 - arxiv.org
We analyze all possible symmetry reductions of Lagrangians that yield fully equivalent field
equations for any 4-dimensional metric theory of gravity. Specifically, we present a complete …
