General Slow-Roll Inflation in <i>f</i>(<i>R</i>) Gravity under the Palatini Approach
Slow-roll inflation is analyzed in the context of modified gravity within the Palatini formalism. As shown in the literature, inflation in this framework requires the presence of non-traceless matter; otherwise, it does not occur just as a consequence of the nonlinear gravitational terms of the acti...
