Interacting Dark Energy and the Expansion of the Universe

This book presentsa high-level study of cosmology with interacting dark energy and no additional fields. It is known that dark energy is not necessarily uniform when other sources of gravity are present: interaction with matter leads to its variation in space and time. The presenttext studies the cosmological implications of this circumstanceby analyzing cosmological models in which the dark energydensity interacts with matter and thus changes with the time.The bookalso includes a translation of a seminalarticle about the remarkable life and work of E.B. Gliner,the first personto suggest the concept of dark energy in 1965.
