Comment on "Einstein-Gauss-Bonnet Gravity in Four-Dimensional Spacetime"
Julio Arrechea, Adrià Delhom, Alejandro Jiménez-Cano
We argue that several statements in Phys. Rev. Lett. 124, 081301 (2020) are not correct.
New metric-affine generalizations of gravitational wave geometries
Alejandro Jiménez-Cano
In this paper we explore generalizations of metric structures of the gravitational wave type to geometries containing an independent connection. The aim is simply to establish a ne…
General Teleparallel Quadratic Gravity
Jose Beltrán Jiménez, Lavinia Heisenberg, Damianos Iosifidis +2
In this Letter we consider a general quadratic parity-preserving theory for a general flat connection. Imposing a local symmetry under the general linear group singles out the gene…
On the topological character of metric-affine Lovelock Lagrangians in critical dimensions
Bert Janssen, Alejandro Jiménez-Cano
In this paper we prove that the -th order metric-affine Lovelock Lagrangian is not a total derivative in the critical dimension in the presence of non-trivial non-metrici…
Geometric inequivalence of metric and Palatini formulations of General Relativity
Cecilia Bejarano, Adria Delhom, Alejandro Jiménez-Cano +2
Projective invariance is a symmetry of the Palatini version of General Relativity which is not present in the metric formulation. The fact that the Riemann tensor changes nontrivia…
