Cosmology in gravity: A unified dynamical systems analysis of the background and perturbations

W Khyllep, J Dutta, EN Saridakis, K Yesmakhanova - Physical Review D, 2023 - APS
Motivated by the fact that cosmological models based on f (Q) gravity are very efficient in
fitting observational datasets at both background and perturbation levels, we perform a …

Late-time cosmology with phantom dark-energy in f (Q) gravity

A Lymperis - Journal of Cosmology and Astroparticle Physics, 2022 - iopscience.iop.org
Motivated by the exciting features and a recent proposed general form of the function of non-
metricity scalar Q, we investigate the cosmological implications in f (Q) gravity, through the …
