Field equations and Noether potentials for higher-order theories of gravity with Lagrangians involving $□^{i} R$ , $□^{i} R_{μν}$ and $□^{i} R_{μν ρ σ}$

Jun-Jin Peng, Hua Li

In this paper, we aim to perform a systematical investigation on the field equations and Noether potentials for the higher-order gravity theories endowed with Lagrangians depending…
