Modified Gravity and Cosmology

摘要: Abstract In this review we present a thoroughly comprehensive survey of recent work on modified theories gravity and their cosmological consequences. Amongst other things, cover General Relativity, scalar–tensor, Einstein–aether, Bimetric theories, as well TeVeS, f ( R ) , general higher-order Hořava–Lifschitz gravity, Galileons, Ghost Condensates, models extra dimensions including Kaluza–Klein, Randall–Sundrum, DGP, higher co-dimension braneworlds. We also attempts to construct Parameterised Post-Friedmannian formalism, that can be used constrain deviations from Relativity in cosmology, is suitable for comparison with data the largest scales. These subjects have been intensively studied over past decade, largely motivated by rapid progress field observational cosmology now allows, first time, precision tests fundamental physics scale observable Universe. The purpose provide reference tool researchers students gravitational physics, self-contained, up-to-date introduction subject whole.
