Gravitation and Modern Cosmology: The Cosmological Constants Problem

Gravitation and Modern Cosmology: The Cosmological Constants Problem by Antonino Zichichi, Venzo Sabbata, Norma Sánchez
English | PDF | 1991 | 232 Pages | ISBN : 0306440547 | 18.67 MB

Peter Gabriel Bergmann started his work on general relativity in 1936 when he moved from Prague to the Institute for Advanced Study in Princeton. Bergmann collaborated with Einstein in an attempt to provide a geometrical unified field theory of gravitation and electromagnetism. Within this program they wrote two articles together: A. Einstein and P. G. Bergmann, Ann. Math. 39, 685 (1938) ; and A. Einstein, V. Bargmann and P. G. Bergmann, Th. von Karman Anniversary Volume 212 (1941).

Relativistic Cosmology: An Introduction

Relativistic Cosmology: An Introduction by Jean Heidmann
English | PDF | 1980 | 170 Pages | ISBN : 3540101381 | 11.2 MB

Since the first French edition of the book emphasized rather the solid facts of Cosmology than the detailed discussions of controversial results, relatively few revisions were necessary for the English edition. They were made early in 1979 and affected about 5% of the text. The main revisions referred to the distance scale, the dlstribution of galaxies, the X-ray observations of clusters, the cosmic time evolution of quasars and radiogalaxies and the 3 K radiation. A new short bibliography presents the recent articles and the latest proceedings of Symposia; from these the reader can easily trace a more complete list of refer­ ences. I am happy to thank Professor Beiglbock for suggestions he made to improve Part lIon Spaces of Constant Curvature, and Drs. S. and J. Mitton for translating the manuscript into English. I also thank with pleasure Marie-Ange Sevin for correcting the final version. J. Heidmann March 1980, Meudon, France Preface The aim of this book is to present the fundamentals of cosmology.

The Universe of Fluctuations: The Architecture of Spacetime and the Universe

The Universe of Fluctuations: The Architecture of Spacetime and the Universe by B.G. Sidharth
English | PDF(True) | 2005 | 193 Pages | ISBN : 1402037856 | 2.85 MB

In 1997, contrary to the ruling paradigm which was that of a dark matter filled, decelerating universe, my work pointed to a dark energy driven accelerating universe with a small cosmological constant. Moreover, the many supposedly accidental Large Number relations in cosmology, including the mysterious Weinberg formula were now deduced from the theory. Observational confirmation for this scenario came in 1998, while dark energy itself was finally reconfirmed in 2003, thanks to the Wilkinson Microwave Anisotropy Probe and the Sloan Digital Sky Survey.

Gravitational Waves from Coalescing Binaries

Gravitational Waves from Coalescing Binaries by Stanislav Babak
English | PDF(True) | 2020 | 117 Pages | ISBN : 1681737027 | 5.4 MB

This book is to help post-graduate students to get into gravitational wave astronomy. We assume the knowledge of General Relativity theory, though we will concentrate on the physics and often omit mathematically strict derivations. We provide references to already existing literature where possible, this helps us to see a broad picture, skipping the details. The uniqueness of this book is in that it covers three frequency bands and three major world-wide efforts to detect gravitational waves.

The Einstein Equations and the Large Scale Behavior of Gravitational Fields

The Einstein Equations and the Large Scale Behavior of Gravitational Fields: 50 Years of the Cauchy Problem in General Relativity by Piotr T. Chruściel
English | PDF | 2004 | 487 Pages | ISBN : 3764371307 | 51.3 MB

The book presents state-of-the-art results on the analysis of the Einstein equations and the large scale structure of their solutions. It combines in a unique way introductory chapters and surveys of various aspects of the analysis of the Einstein equations in the large. It discusses applications of the Einstein equations in geometrical studies and the physical interpretation of their solutions. Open problems concerning analytical and numerical aspects of the Einstein equations are pointed out.

Quantum Gravity

Quantum Gravity by M. A. Markov
English | PDF | 1984 | 543 Pages | ISBN : 1461296781 | 21.5 MB

Three years have passed after the First Moscow Seminar on Quantum Gravity. It is a rather long time interval for the modern theoretical physics. The talks given at the present Second Seminar which took place in October 13-15, 1981 in Moscow contain the discussion of new results obtained during this period and the problems which arose. More than one hundred Soviet scientists and a number of the foreign guests attended this Seminar, which as the previous one was held by the Nuclear Physics Department of the Academy of Sciences of the USSR and the Institute for Nuclear Research of the Academy of Sciences of the USSR.

General Relativity and Matter: A Spinor Field Theory from Fermis to Light-Years by Mendel Sachs
English | PDF | 1982 | 224 Pages | ISBN : 9048183707 | 21 MB

There exist essentially two levels of investigation in theoretical physics. One is primarily descriptive, concentrating as it does on useful phenomenological approaches toward the most economical classifications of large classes of experimental data on particular phenomena. The other, whose thrust is explanatory, has as its aim the formulation of those underlying hypotheses and their mathematical representations that are capable of furnishing, via deductive analysis, predictions - constituting the particulars of universals (the asserted laws)- about the phenomena under consideration.

English | PDF | 2006 | 288 Pages | ISBN : 3540310274 | 4.1 MB

Today, general relativity rates among the most accurately tested fundamental theories in all of physics. However, deficiencies in our mathematical and conceptual understanding still exist, and these partly hamper further progress.

Classical and Quantum Cosmology (Repost)

Classical and Quantum Cosmology By Gianluca Calcagni
English | EPUB | 2017 | 843 Pages | ISBN : 331941125X | 8.6 MB

This comprehensive textbook is devoted to classical and quantum cosmology, with particular emphasis on modern approaches to quantum gravity and string theory and on their observational imprint. It covers major challenges in theoretical physics such as the big bang and the cosmological constant problem. An extensive review of standard cosmology, the cosmic microwave background, inflation and dark energy sets the scene for the phenomenological application of all the main quantum-gravity and string-theory models of cosmology.

Quantum Mechanics of Fundamental Systems: The Quest for Beauty and Simplicity: Claudio Bunster Festschrift by Jorge Zanelli
English | PDF | 300 Pages | ISBN : 0387874984 | 3.6 MB

In life and work, Claudio Bunster (formerly Teitelboim) prefers extreme challenges. Bunster, a physicist who contemplates brain-warping theories of space and time, returned to his native Chile from the United States precisely when most intellectuals would have stayed clear— during the middle of the Pinochet dictatorship (K. Mossman, Proceedings of the National Academy of Sciences)
