Beyond Einstein's Gravity is a graduate level introduction to
extended theories of gravity and cosmology, including variational
principles, the weak-field limit, gravitational waves, mathematical
tools, exact solutions, as well as cosmological and astrophysical
applications. The book provides a critical overview of the research
in this area and unifies the existing literature using a consistent
notation. Although the results apply in principle to all
alternative gravities, a special emphasis is on scalar-tensor and
f(R) theories. They were studied by theoretical physicists from
early on, and in the 1980s they appeared in attempts to renormalize
General Relativity and in models of the early universe. Recently,
these theories have seen a new lease of life, in both their metric
and metric-affine versions, as models of the present acceleration
of the universe without introducing the mysterious and exotic dark
energy. The dark matter problem can also be addressed in extended
gravity. These applications are contributing to a deeper
understanding of the gravitational interaction from both the
theoretical and the experimental point of view. An extensive
bibliography guides the reader into more detailed literature on
particular topics.
