Abstract
The two main classes of ETGs considered in this book, scalar-tensor and f(R) gravity, are the subject of much of this chapter. After exposing the metric formalism, due consideration is given to the Palatini version of f(R) theories, emphasizing its bimetric nature. Specifically, we present the actions describing ETGs, derive the field equations from a variational principle, and then discuss their different conformal representations. In this chapter the emphasis is on the general structure of these theories, while their application to astrophysics and cosmology is studied in later chapters.
