Inverse non-metricity in $f(Q)$ gravity: cosmology and observational constraints

Luís Atayde, Simão Marques Nunes, Noemi Frusciante

We study a minimal modified gravity scenario in the symmetric teleparallel (non-metricity) formulation, focusing on an inverse non-metricity term with $f(Q)=Q+M^4{Q}^{-1}$. The mode…
