Book Description
We live in this universe. Hence, it is essential to understand the origin, evolution and ultimate fate of the universe. This can be, effectively, done by constructing mathematical models of the universe, using Einstein's theory of gravitation and other modified theories of gravitation. The models, thus, obtained can be compared with the present day observations, to decide about the shape, physics, and origin of the universe. With this motivation we have taken up the investigations in this book entitled "STUDIES ON GRAVITATIONAL FIELD EQUATIONS AND IMPORTANT RESULTS OF RELATIVISTIC COSMOLOGY". This book comprises of six chapters and deals with some spatially homogeneous isotropic and anisotropic cosmological models of the universe in some modified theories of gravitation.

Black Holes, Cosmology And Extra Dimensions (Second Edition)
Author: Kirill A Bronnikov
Publisher: World Scientific
ISBN: 9811233462
Category : Science
Languages : en
Pages : 591
Book Description
Assuming basic knowledge of special and general relativity, this book guides the reader to problems under consideration in modern research, concerning black holes, wormholes, cosmology, and extra dimensions. Its first part is devoted to local strong field configurations (black holes and wormholes) in general relativity and its most relevant extensions: scalar-tensor, f(R), and multidimensional theories. The second part discusses cosmology, including inflation and problems of a unified description of the whole evolution of the universe. The third part concerns multidimensional theories of gravity and contains a number of original results obtained by the authors. Expository work is conducted for a mechanism of symmetries and fundamental constants formation. The original approach to nonlinear multidimensional gravity that is able to construct a unique perspective describing different phenomena is highlighted.Much of the content was previously presented only in journal publications and is new for book contents, e.g., on regular black holes, various scalar field solutions, wormholes and their stability, inflation, clusters of primordial black holes, and multidimensional gravity. The last two topics are added in this new edition of the book. The other chapters are also updated to include new discoveries like the detection of gravitational waves.

The New Cosmology
Author: Roland E. Allen
Publisher: American Institute of Physics
ISBN:
Category : Science
Languages : en
Pages : 476
Book Description
The papers in this volume examine the recent revolutionary discoveries in cosmology and astronomy, and their theoretical interpretation. The observational evidence for an accelerating universe, and an earlier decelerating phase, is brought up to date with the newest results for the most distant and oldest Type Ia supernovae. The data from the WMAP satellite provide, for the first time, true precision cosmology: reliable results for the age of the universe, its geometry, its evolution over the past 13.7 billion years, and many other features, including the proportions of ordinary matter, dark matter, and dark energy. Other papers in this volume describe the information obtained with 21st century astronomical techniques, including gravitational lensing, studies across the electromagnetic spectrum with ground-based and NASA observatories, and surveys of millions of galaxies. The results are interpreted by leading theorists using both accepted and exotic theories, including inflation and superstring theory.

Gravitation and Cosmology

Publisher: John Wiley & Sons
ISBN:
Category : Science
Languages : en
Pages : 696
Book Description
Weinberg's 1972 work, in his description, had two purposes. The first was practical to bring together and assess the wealth of data provided over the previous decade while realizing that newer data would come in even as the book was being printed. He hoped the comprehensive picture would prepare the reader and himself to that new data as it emerged. The second was to produce a textbook about general relativity in which geometric ideas were not given a starring role for (in his words) too great an emphasis on geometry can only obscure the deep connections between gravitation and the rest of physics.
