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
Multipole expansion — A multipole expansion is a mathematical series representing a function that depends on angles usually the two angles on a sphere. These series are useful because they can often be truncated, meaning that only the first few terms need to be… … Wikipedia
BKL singularity — A BKL (Belinsky Khalatnikov Lifshitz) singularityHarvnb|Belinsky|Khalatnikov|Lifshitz|1970] is a model of the dynamic evolution of the Universe near the initial singularity, described by a non symmetric, chaotic, vacuum solution to Einstein s… … Wikipedia
Linearized gravity — is an approximation scheme in general relativity in which the nonlinear contributions from the spacetime metric are ignored. This allows the study of many problems to be simplified. The methodIn linearized gravity, the metric tensor of spacetime… … Wikipedia

Exact solutions in general relativity — In general relativity, an exact solution is a Lorentzian manifold equipped with certain tensor fields which are taken to model states of ordinary matter, such as a fluid, or classical nongravitational fields such as the electromagnetic field.… … Wikipedia
Monitoring and Measurement in the Next Generation Technologies — (MOMENT) is a project aimed at integrating different platforms for network monitoring and measurement to develop a common and open pan European infrastructure. The system will include both passive and active monitoring and measurement techniques… … Wikipedia
Nordström's theory of gravitation — In theoretical physics, Nordström s theory of gravitation was a predecessor of general relativity. Strictly speaking, there were actually two distinct theories proposed by the Finnish theoretical physicist Gunnar Nordström, in 1912 and 1913… … Wikipedia
Newtonian gauge — For context, see also scalar vector tensor decomposition and cosmological perturbation theory. In general relativity, Newtonian gauge is a perturbed form of the Friedmann Lemaitre Robertson Walker line element. The gauge freedom of general… … Wikipedia
