# Cosmological evolution in Weyl conformal geometry

@inproceedings{Ghilencea2021CosmologicalEI, title={Cosmological evolution in Weyl conformal geometry}, author={Dumitru M. Ghilencea and Tiberiu Harko}, year={2021} }

We discuss the cosmological evolution of the Weyl conformal geometry and its associated Weyl quadratic gravity. The Einstein gravity (with a positive cosmological constant) is recovered in the spontaneously broken phase of Weyl gravity; this happens after the Weyl gauge field (ωμ) of scale symmetry, that is part of the Weyl geometry, becomes massive by Stueckelberg mechanism and decouples. This breaking is a natural result of the cosmological evolution of Weyl geometry, in the absence of matter…
