This book presents a clear and accessible introduction to the theory of cosmological perturbations. This subject is central to modern cosmology, since scalar cosmological perturbations in the early universe are believed to be the seeds from which today's cosmological structures, such as galaxies and clusters of galaxies, originated.The text begins with an introduction to the fundamentals of Einstein's theory of general relativity and the key elements of the standard cosmological model. The basic ideas of cosmological perturbations and gravitational instability are first developed within a Newtonian framework, providing an intuitive foundation for the fully relativistic treatment presented in later chapters. The final part of the book explores specific models and generalizations of the standard model, including non-adiabatic pressure perturbations, non-standard dark-matter and dark-energy models, as well as dissipative phenomena.Providing a concise yet wide-ranging treatment of the subject, this book serves as an ideal entry point for graduate students and researchers who wish to build the foundations necessary to explore cosmological perturbation theory in greater depth.

The series of texts composing this book is based on the lectures presented during the II José Plínio Baptista School of Cosmology, held in Pedra Azul (Espírito Santo, Brazil) between 9 and 14 March 2014. This II JBPCosmo has been entirely devoted to the problem of understanding theoretical and observational aspects of Cosmic Background Radiation (CMB).The CMB is one of the most important phenomena in Physics and a fundamental probe of our Universe when it was only 400,000 years old. It is an extraordinary laboratory where we can learn from particle physics to cosmology; its discovery in 1965 has been a landmark event in the history of physics.The observations of the anisotropy of the cosmic microwave background radiation through the satellites COBE, WMAP and Planck provided a huge amount of data which are being analyzed in order to discover important informations regarding the composition of our universe and the process of structure formation.
