This paper describes a general-purpose algorithm for computing the gradients in space and time of a scalar field, a vector field, or a divergence-free vector field, from in situ measurements by one or more spacecraft. The algorithm provides total error estimates on the computed gradient, ...
(2.13) is often called the derivative or Jacobian matrix of the vector field V. Notice that there is a subtle difference between the gradient of a vector and the definition of the dyadic product with the gradient operator, if it is considered to be a vector. Specifically, by convention, ...
Vector functions: The vector function (aka a vector field) is a function which returns a vector at each location of space. Examples include the gravitational field (at each location we have a different vector defining the local acceleration of gravity), the electric field, the velocity field of...

theory [54]. However, ones have regardedfab, in analogy toGab, as a metric of vector field space [83]. Both of these metrics have been assumed to be functions of scalar fields in Ref. [83]. In this paper, the scalar field and vector field spaces will be assumed to be two-...
Or do I mess up something with the dimensions? This is a more detailed description in the potential() function: % P = POTENTIAL(V,X,Y) computes the potential of vector field V with % respect to X using Y as base point for the integration. If Y...
{\mu \nu }\)which breaks the conformal invariance. As a result, the existence of the non-trivial function\(f(\phi )\)prevents the vector field from an exponential dilution during the inflationary phase. Hence, the existence of the non-vanishing vector field will lead to small spatial ...
Scalar and massless vector fields in Cartan space 来自 dx.doi.org 喜欢 0 阅读量: 32 作者: M Novello 摘要: By assuming the existence of a relation between spin and torsion, a scalar field cannot couple with Cartan geometry. This is well achieved by imposing the minimum coupling principle...
