Ricci-Determinant Gravity: Dynamical Aspects and Astrophysical Implications

Hemza Azri, K. Yavuz Ekşi, Canan Karahan +1

The Palatini gravitational action is enlarged by an arbitrary function $f(X)$ of the determinants of the Ricci tensor and the metric, $X=|\text{det}.R|/|\text{det}.g|$. The res…
