abstract

We study the evolution of the physical variables in $f\left( Q\right) $-gravity for two families of symmetric and flat connections in a spatially flat Friedmann--Lema\^{\i}tre--Robertson--Walker geometry where the equation of motion for the nonmetricity scalar is not trivially identity. From the analysis of dynamics we found that the de Sitter universe is always an attractor while the cosmological models admit scaling solutions which can describe the early acceleration phase of our universe or the matter and the radiation epochs.

  1. Degenerate and connection-dependent cosmological sectors in f(Q,C) gravity

    gr-qc 2026-07 conditional novelty 6.0 of 10

    Connection field equations force a degenerate f(R)-equivalent sector of f(Q,C) cosmology in which three geometric connections coincide, and only nonzero integration constants make the connections physically distinct.

  2. Decoupling perturbations from background in $f(Q)$ gravity: the square-root correction and the impact on the $\sigma_8$ tension

    astro-ph.CO 2025-12 conditional novelty 4.0 of 10

    A sqrt(Q) correction in f(Q) gravity suppresses structure growth without altering the expansion history; fitted to RSD/DESI data it can bring sigma8 into agreement with Planck, at the cost of a sigma8-M degeneracy.
