Abstract
In this chapter we focus again on scalar-tensor and f(R) gravity. We begin by studying the phase space of spatially homogenous and isotropic scalar-tensor (and, by extension, f(R) cosmology. Understanding the structure of the phase space is extremely useful when exact solutions cannot be obtained, or when one needs to know whether known solutions are generic or not. After a general discussion of the geometry of the phase space, we continue by examining particular analytical solu- tions of scalar-tensor and metric f(R) gravity.While these rare exact solutions may be very special, they still allow us to gain insight into the properties of these ETGs.
