Modified Gravity and Cosmology

The book "Modified Gravity and Cosmology" provides a comprehensive overview of the latest developments in the fields of gravitation and cosmology, with a particular focus on modified gravity theories. It highlights the current challenges and open questions in theoretical physics and indicates the directions in which future research may trend. The authors analyze various extended theories and scenarios regarding their theoretical consistency and apply them to different geometric backgrounds, including cosmological and spherically symmetric models. The predictions of these theories are examined at both background and perturbation levels and compared with the extensive observational data from the last two decades. The book classifies the theories that successfully pass these tests as viable and offers readers a clear overview of the current state of research and future developments in the field of modified gravity.
