Scalar field theory as a theory of gravitation. by Paul Edwin Kustaanheimo Download PDF EPUB FB2

Scalar theories of gravitation are field theories of gravitation in which the gravitational field is described using a scalar field, which is required to satisfy some field equation. Note: This article focuses on relativistic classical field theories of gravitation.

The best known relativistic classical field theory of gravitation, general relativity, is a tensor theory, in which the.

In theoretical physics, a scalar–tensor theory is a field theory that includes both a scalar field and a tensor field to represent a certain interaction. For example, the Brans–Dicke theory of gravitation uses both a scalar field and a tensor field to mediate the gravitational interaction.

We also explain the notation and the system of units to be used in this book. The list of the fundamental ideas sketched in section 2 includes the Kaluza–Klein (KK) theory, string theory, brane theory as the latest out-growth of string theory, and a conjecture on two-sheeted space-time.

the standard theory of gravitation, the theory has also nurtured many “alternative theories” for one reason or another.

Among them we focus particularly on the “scalar–tensor theory.” It might appear as if the old idea of scalar gravity were being resurrected. In fact, however, this type. The scalar-tensor theory of gravitation moved into the limelight in recent years due to developments in string theory, M-theory and 'brane world' constructions.

This book introduces the subject at a level suitable for both graduate students and researchers. It explores scalar fields, placing them in context with a discussion of Brans-Dicke.

to the book by Weinberg for the classical theory of gravitation developed from this point of view. Our starting point will be that gravitation is caused by a particle of spin two. The reasons for that have been given at many occasions, and may be summa-rized as follows: (i) The gravitational field cannot be described by a vector field such as the.

The scalar-tensor theory of gravitation moved into the limelight in recent years due to developments in string theory, M-theory and "brane world" constructions.

This book introduces the subject at a level suitable for both graduate students and researchers. It explores scalar fields, placing them in context with a discussion of Brans-Dicke theory, covering the cosmological constant problem.

The preferred reference frame of the theory is that one which is Scalar field theory as a theory of gravitation. book by averaging the velocity field of the micro-ether over a very large scale.

An equation for the scalar gravitational field p e (or equivalently the field ρ e) follows from the requirement that Newtonian gravity should be recovered if the micro-ether were an.

A scalar theory of gravitation is developed from a variational principle. The speed of light is taken to be a function of the potential of the gravitational field. The predictions of the light deflection and the advancement of the perihelion agree with those made by Einstein's theory. The gravitational (active) mass differs from the inertial (passive) mass and both are dependent on the Cited by: 4.

An alternative, scalar theory of gravitation has been proposed, based on a mechanism/interpretation of gravity as being a pressure force: Archimedes’ thrust. In it, the gravitational field affects the physical standards of space and time, but motion is governed by an.

For several decades since its inception, Einstein's general theory of relativity stood somewhat aloof from the rest of physics. Paradoxically, the attributes which normally boost a physical theory - namely, its perfection as a theoreti cal framework and the extraordinary intellectual achievement underlying i- prevented the general theory from being assimilated in the mainstream of physics.5/5(1).

To my knowledge The Scalar-Tensor Theory of Gravitation by Y Fujii and K Maeda is the first book to develop a modern view on this topic and is one of the latest titles in the well-presented Cambridge Monographs on Mathematical Physics series. This book is an excellent readable introduction and up-to-date review of the subject.

Another very striking feature of Nordström's theory is that it while it can be written as the theory of a certain scalar field in Minkowski spacetime, and in this form enjoys the expected conservation law for nongravitational mass-energy together with gravitational field energy, but suffers from a not very memorable force law, in the curved spacetime formulation the motion of test particles.

The scalar-tensor theory of gravitation moved into the limelight in recent years due to developments in string theory, M-theory and 'brane world' constructions. This book introduces the subject at a level suitable for both graduate students and researchers.

It explores scalar fields, placing them in context with a discussion of Brans-Dicke theory, covering the cosmological constant problem. Introduction Several new theories of gravitation have been formulated which are considered to be alternative to Einstein's theory of gravitation.

In alternative theories of gravitation, scalar tensor theories proposed by Brans and Dicke [1], Nordvedt [2], Wagoner [3], Ross [4], Dunn [5] and Saez and Ballester [6] are most important among them. What is the scalar–tensor theory of gravitation.

Einstein’s general theory of relativity is a geometrical theory of space-time. The fundamental building block is a metric tensor field. For this reasonthetheorymaybecalleda“tensortheory.”A“scalartheory”of gravity had earlier been attempted by G.

It will also provide a valuable reference for researchers."--BOOK JACKET. The Scalar–Tensor Theory of Gravitation The scalar–tensor theory of gravitation is one of the most popular alternatives to Einstein’s theory of gravitation.

This book provides a clear and concise introduction to the theoretical ideas and developments, exploring scalar fields and placing them in con-text with a discussion of Brans–Dicke. The scalar-tensor theory of gravitation moved into the limelight in recent years due to developments in string theory, M-theory and "brane world" constructions.

This book introduces the subject at a level suitable for both graduate students and researchers. Gravitation and Gauge Symmetries sheds light on the connection between the intrinsic structure of gravity and the principle of gauge invariance, which may lead to a consistent unified field theory.

The first part of the book gives a systematic account of the structure of gravity as a theory based on spacetime gauge symmetries. The scalar-tensor theory of gravitation is one of the most popular alternatives to Einstein's theory of gravitation.

The most basic scalar field theory is the linear theory. Through the Fourier decomposition of the fields, it represents the normal modes of an infinity of coupled oscillators where the continuum limit of the.

The covariant theory of gravitation (CTG) appeared in [1], as a consequence of the relativistic generalization of the Lorentz-invariant theory of gravitation (LITG). LITG equations are similar by their form to Maxwell's equations and can be derived on the basis of axioms [2].

In a scalar field theory of gravity is an interpretation of gravity as the curvature of spacetime necessary. Also, experimentally, what are the failures of a scalar theory of gravity. Also, how about a vector theory of gravity,similar to Maxwell's equations. $\endgroup$ – guru Oct 2 '13 at methods of classical relativistic eld theory.

Scalar elds, spinor elds, gauge elds, and gravitational elds are treated. The material is based upon lecture notes for a course I teach from time to time at Utah State University on Classical Field Theory.

This version,is. To me the simple generalization of Newton’s gravitation theory made by Nordstrom (called Nordstrom’s gravitation theory) is much more likely to be correct.

The reasons are the following: ` 1. Nordstrom’s theory is a scalar theory and a scalar quantum field can very well be included in a renormalizable quantum field theory.

If you want to entertaining books, lots of novels. status of a scalar theory of gravitation, which is a preferred-frame theory based on a new concept of ether.

We shall begin with an account of the current motivation for reintroducing an ether. The first reason is to extend the Lorentz-Poincaré ether theory to gravitation.

Still today, most. General relativity, like electromagnetism, is a classical field might expect that, as with electromagnetism, the gravitational force should also have a corresponding quantum field theory. However, gravity is perturbatively nonrenormalizable.: xxxvi–xxxviii;– For a quantum field theory to be well defined according to this understanding of the subject, it must be.

In the Brans-Dicke theory the reciprocal of the gravitational constant is itself a one-component field, the scalar field, that is generated by matter in accordance with an additional equation.

Then as well as matter has a say in determining the metric via a modified version of Einstein's equations. The canonical theory of gravity together with the scalar field is written as a combined variable theory in ADM form, in the classical and quantum theory.

FLRW $κ= 0$ cosmology is rewritten in the combined variable theory. Newtonian gravitation can be written as the theory of a scalar field, Φ, which is the gravitational potential in joules per kilogram of the gravitational field g = −∇Φ, see Gauss's law for gravity ∇.

Others include: Gauss–Bonnet gravity, f(R) gravity, and Lovelock theory of gravity. Scalar-tensor theories. These all contain at least one free parameter, as opposed to GR which has no free parameters. Although not normally considered a Scalar-Tensor theory of gravity, the 5 by 5 metric of Kaluza-Klein reduces to a 4 by 4 metric and a single.

But SR does not describe gravitation. An alternative theory of gravi-tation has been proposed, that o ers a mechanism/interpretation allowing to understand gravity as being a pressure force: Archimedes’ thrust [9, 10].

1 It is thus a scalar theory but an original one (see below), and it is a preferred-frame theory. The topics of quantum field theory on curved backgrounds, the ADM formulation and a brief introduction of the Horava–Lifshitz quantum gravity are also presented.

A standard discussion of the cosmological constant problem is found in the classic paper [ 1 ], and a lucid presentation of the current observational and theoretical status of dark. 5. A short guide to the new scalar theory of gravitation.

To a review on ether theories of gravity, with the scalar theory reviewed in more detail. The currently accepted theory of gravitation is Einstein's general relativity, which arose after a decade of research trying to make gravitation compatible with relativity.

Once the heart of the.A scalar‐tensor theory of gravitation is constructed using a non‐Riemannian geometry in which both the metric tensor and the scalar function have an unambiguous geometric interpretation. The scalar function is introduced by defining a linear connection with nonvanishing torsion.

The field equations of the theory, and the Lagrangian from which they are derived, are identical to those given. A closed‐form exact solution to the field equations of a scalar‐tensor theory, formally similar to the Brans‐Dicke theory, is obtained.

It is shown that the present theory predicts the same effects, within observational limits, as the Einstein theory.
