Pseudotensor — In physics and mathematics, a pseudotensor is usually a quantity that transforms like a tensor under a proper rotation, but gains an additional sign flip under an improper rotation (a transformation that can be expressed as an inversion followed… … Wikipedia
Pseudotensor — Ein Axialvektor oder axialer Vektor, auch Pseudovektor genannt, ist in der Physik eine vektorielle Größe, welche bei einer Punktspiegelung des untersuchten physikalischen Systems unverändert bleibt. Zur Unterscheidung nennt man einen Vektor polar … Deutsch Wikipedia
Stress-energy-momentum pseudotensor — In the theory of general relativity, a stress energy momentum pseudotensor, such as the Landau Lifshitz pseudotensor, is an extension of the non gravitational stress energy tensor which incorporates the energy momentum of gravity. It allows the… … Wikipedia
Pseudoscalar — In physics, a pseudoscalar is a quantity that behaves like a scalar, except that it changes sign under a parity inversion such as improper rotations while true scalar does not.The prototypical example of a pseudoscalar is the scalar triple… … Wikipedia
Stress-energy tensor — The stress energy tensor (sometimes stress energy momentum tensor) is a tensor quantity in physics that describes the density and flux of energy and momentum in spacetime, generalizing the stress tensor of Newtonian physics. It is an attribute of … Wikipedia
