In this paper, we develop a geometric generalization of General Relativity based on the semi-
symmetric metric connection introduced by Friedmann and Schouten in 1924. Although the …

It is recalled how relationality arises as the core insight of general‐relativistic gauge field
theories from the articulation of the generalized hole and point‐coincidence arguments …

Cosmological implications of a generalized Rastall theory where the nonconservation
equation is promoted to accept arbitrary functions of the Ricci scalar is considered. We have …

We make a case for the unique relevance of Cartan geometry for gauge theories of gravity
and supergravity. We introduce our discussion by recapitulating historical threads, providing …

We investigate the effect of particle creation in flat Friedmann-Lemaitre-Robertson-Walker
(FLRW) spacetime under the higher derivative theory composition. The exact solution of the …

We study the exterior solution for a static, spherically symmetric source in Weyl conformal
gravity in terms of the Newman-Penrose formalism. We first show that both the static …

Gauge symmetries are a cornerstone of modern physics but they come with technical
difficulties when it comes to quantization, to accurately describe particles phenomenology or …

We consider the cosmological implications of a gravitational theory containing two vector
fields coupled via a generalized Chern–Simons term. One of the vector fields is the usual …

The on shell equivalence of first order and second order formalisms for the Einstein-Hilbert
action does not hold for those actions quadratic in curvature. It would seem that by …

We investigate whether a spontaneously-broken gauge theory of the group $ SU (2, 2) $
may be a viable alternative to general relativity. The basic ingredients of the theory are an …
