Implications of extreme flatness in a general f(R) theory

We discuss a modified gravity theory defined by f(R)=∑nlαnM2(1−n)Rn. We consider both finite and infinite number of terms in the series while requiring that the Einstein frame potential of the theory has a flat area around any of its stationary points. We show that the requirement of maximally flat...
