COSMOLOGICAL MODELS Cargèse Lectures 1998

چکیده
The aim of this set of lectures is a systematic presentation of a 1 + 3 covariant approach to studying the geometry, dynamics, and observational properties of relativistic cosmological models. In giving (i) the basic 1 + 3 covariant relations for a cosmological fluid, the present lectures cover some of the same ground as a previous set of Cargèse lectures [7], but they then go on to give (ii) the full set of corresponding tetrad equations, (iii) a classification of cosmological models with exact symmetries, (iv) a brief discussion of some of the most useful exact models and their observational properties, and (v) an introduction to the gauge-invariant and 1+3 covariant perturbation theory of almost-Friedmann–Lemâıtre–Robertson–Walker universes, with a fluid description for the matter and a kinetic theory description of the radiation.

متن کاملIntersection Theory , Integrable Hierarchies and Topological Field Theory ∗
In these lecture notes we review the various relations between intersection theory on the moduli space of Riemann surfaces, integrable hierarchies of KdV type, matrix models, and topological field theory. We focus in particular on the question why matrix integrals of the type considered by Kontsevich naturally appear as τ -functions of integrable hierarchies related to topological minimal model...
متن کاملDark Matter and Large-scale Structure
The three parts of this paper cover the following topics: (1) status of the cosmological parameters H0, t0, , and especially ; (2) how to compare cosmological theories of structure formation and cosmological simulations to observational data; and (3) structure formation in Cold Dark Matter (CDM) and related cosmological models, especially Cold + Hot Dark Matter (CHDM). I will also brie y discus...
متن کاملClassical Geometry and Target Space Duality
A new formulation for a “restricted” type of target space duality in classical two dimensional nonlinear sigma models is presented. The main idea is summarized by the analogy: euclidean geometry is to riemannian geometry as toroidal target space duality is to “restricted” target space duality. The target space is not required to possess symmetry. These lectures only discuss the local theory. Th...
