It covers all the standard observables, i.e. distances, weak lensing, number counts and cosmic microwave background, and also includes a detailed derivation of general-relativistic matrix kinetic theory. All the fully nonlinear equations are derived in detail and the mathematical content is self-contained, so that readers require only a basic knowledge of general relativity. Moreover, the authors discuss several subtle issues that are usually overlooked in the literature and, in particular, issues that distinguish this formalism from the more approximative standard practice.SpringerBriefs in Physics,2191-5423CosmologyGravitationCosmologyhttps://scigraph.springernature.com/ontologies/product-market-codes/P22049Classical and Quantum Gravitation, Relativity Theoryhttps://scigraph.springernature.com/ontologies/product-market-codes/P19070Cosmology.Gravitation.Cosmology.Classical and Quantum Gravitation, Relativity Theory.523.10151Mitsou Ermisauthttp://id.loc.gov/vocabulary/relators/aut805197Yoo Jaiyulauthttp://id.loc.gov/vocabulary/relators/autMiAaPQMiAaPQMiAaPQBOOK996418171503316Tetrad Formalism for Exact Cosmological Observables2141300UNISA01451nam 2200397z- 450 991069394070332120161209105329.0(CKB)5860000000022795(BIP)013468528(EXLCZ)99586000000002279520220406c2005uuuu -u- -engFailure to protect child safety hearing before the Subcommittee on Human Resources of the Committee on Ways and Means, U.S. House of Representatives, One Hundred Eighth Congress, second session, June 17, 20041 online resource (iii, 57 p.) ill0-16-072812-6 Failure to protect child safety Child welfareMarylandBaltimoreEvaluationChild abuseMarylandBaltimorePreventionChildrenServices forMarylandBaltimoreEvaluationFoster home careUnited StatesEvaluationChild welfareUnited StatesChild welfareChild abuseChildrenFoster home carePolitical scienceSocial scienceChild welfareEvaluation.Child abusePrevention.ChildrenServices forEvaluation.Foster home careEvaluation.Child welfareBOOK9910693940703321Failure to protect child safety3187300UNINA
