Cosmology of Metric-Affine Gravity with Pure Shear Hypermomentum
Damianos Iosifidis, Ratbay Myrzakulov, Lucrezia Ravera
In this paper we study the cosmological aspects of metric-affine gravity with hyperfluid. The equations of motion of the theory are obtained by varying the action with respe…

Friedmann-like universes with non-metricity
Damianos Iosifidis, Ioannis Georgios Vogiatzis, Christos G. Tsagas
We study the potential effects of spacetime non-metricity in cosmology. In the spirit of Einstein-Cartan gravity, but with non-metricity replacing torsion, we consider the Einstein…
