General teleparallel quadratic gravity
Jose Beltrán Jiménez,Lavinia Heisenberg,Damianos Iosifidis,Alejandro Jiménez-Cano,Tomi Koivisto,Tomi Koivisto +5 more
TL;DR: In this article, a general quadratic parity-preserving theory for a general flat connection is considered and the viability of the theory is explored by studying the spectrum around Minkowski.

Inconsistencies in four-dimensional Einstein-Gauss-Bonnet gravity
TL;DR: In this paper, the authors argue that the limiting procedure outlined in [Phys. Rev. Lett. 124, 081301 (2020) generally involves ill-defined terms in the four dimensional field equations.

On the (non-)uniqueness of the Levi-Civita solution in the Einstein–Hilbert–Palatini formalism
Antonio N. Bernal,Bert Janssen,Alejandro Jiménez-Cano,José Alberto Orejuela,Miguel Sánchez,Pablo Sánchez-Moreno +5 more
TL;DR: In this article, the authors studied the most general solution for affine connections that are compatible with the variational principle in the Palatini formalism for the Einstein-Hilbert action (with possible minimally coupled matter terms).

Yet another comment on four-dimensional Einstein-Gauss-Bonnet gravity
TL;DR: In this article, it was shown that the limiting procedure outlined in [Phys. Rev. Lett. 124, 081301 (2020) is not well defined as it generally produces divergent terms in the four dimensional field equations.

Geometric inequivalence of metric and Palatini formulations of General Relativity
Cecilia Bejarano,Adrià Delhom,Alejandro Jiménez-Cano,Gonzalo J. Olmo,Gonzalo J. Olmo,Diego Rubiera-Garcia +5 more
TL;DR: In this article, the authors show that for the Schwarzschild solution there exists a projective gauge in which the (affine) Kretschmann scalar, K (R beta mu nu R alpha beta m nu)-R-alpha, can be set to vanish everywhere.
