Dynamical and Observational Analysis of Generalized Nash's Theory of Gravity

Amin Rezaei Akbarieh, Mohammad Amin Bolouri, Yaghoub Heydarzade

We investigate cosmic evolution in generalized Nash's theory of gravity involving the quadratic Ricci invariant $\ddot{I}‡=R_{\hat{I}¼\hat{I}½}{R}^{\hat{I}¼\hat{I}½}$. The analysis is divided into two complementar…
