This work is mainly devoted to constructing a multisymplectic description of Lovelock’s gravity, which is an extension of General Relativity. We establish the Griffiths variational problem for the Lovelock Lagrangian, ...

We study the finite time singularity correspondence between the Jordan and Einstein frames for various F(R) gravity theories. Particularly we investigate the ordinary pure F(R) gravity case and the unimodular F(R) gravity ...

We compute the holographic stress tensor and the logarithmic energy-momentum tensor of Einstein-Weyl gravity at the critical point. This computation is carried out performing a holographic expansion in a bulk action ...
