Cosmology in the mimetic higher-curvature $f(R,R_{\mu \nu }{R}^{\mu \nu })$ gravity

Adam Zenon Kaczmarek, Dominik Szczęśniak

In the framework of the mimetic approach, we study the $f(R,R_{\mu \nu }{R}^{\mu \nu })$ gravity with the Lagrange multiplier constraint and the scalar potential. We introduce field equations fo…
