Scalar-tensor theory — Scalar tensor theories are theories that include a scalar field as well as a tensor field to represent an interaction, especially the gravitational one. Tensor fields and field theory Modern physics tries to derive all physical theories from as… … Wikipedia
Scalar-tensor-vector gravity — (STVG) is a theory of gravity which, like other theories including Modified Newtonian dynamics (otherwise known as MOND ), attempts to explain the rotation of galaxies by doing away with dark matter. Unlike MOND, STVG explains galactic clustering … Wikipedia
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… … Wikipedia
Scalar field — In mathematics and physics, a scalar field associates a scalar value, which can be either mathematical in definition, or physical, to every point in space. Scalar fields are often used in physics, for instance to indicate the temperature… … Wikipedia
Tensor-vector-scalar gravity — (TeVeS) is a proposed relativistic theory which purports to explain galactic rotation curves without invoking dark matter. Originated by Jacob Bekenstein in 2004, it incorporates various dynamical and non dynamical tensor fields, vector fields… … Wikipedia
Scalar curvature — In Riemannian geometry, the scalar curvature (or Ricci scalar) is the simplest curvature invariant of a Riemannian manifold. To each point on a Riemannian manifold, it assigns a single real number determined by the intrinsic geometry of the… … Wikipedia
Scalar field solution — In general relativity, a scalar field solution is an exact solution of the Einstein field equation in which the gravitational field is due entirely to the field energy and In general relativity, the geometric setting for physical phenomena is a… … Wikipedia
Tensor — For other uses, see Tensor (disambiguation). Note that in common usage, the term tensor is also used to refer to a tensor field. Stress, a second order tensor. The tensor s components, in a three dimensional Cartesian coordinate system, form the… … Wikipedia
Tensor contraction — In multilinear algebra, a tensor contraction is an operation on one or more tensors that arises from the natural pairing of a finite dimensional vector space and its dual. In components, it is expressed as a sum of products of scalar components… … Wikipedia
Scalar-vector-tensor decomposition — In cosmological perturbation theory, the scalar vector tensor decomposition is a decomposition of the most general linearized s of the Friedmann Robertson Walker metric into components according to their transformations under spatial rotations.… … Wikipedia
Tensor product — In mathematics, the tensor product, denoted by otimes, may be applied in different contexts to vectors, matrices, tensors, vector spaces, algebras, topological vector spaces, and modules. In each case the significance of the symbol is the same:… … Wikipedia
