In differential geometry, the Weyl curvature tensor, named after Hermann Weyl, is a measure of the curvature of spacetime or, more generally, a pseudo-Riemannian manifold. Like the Riemann curvature tensor, the Weyl tensor expresses the tidal force that a body feels when moving along a geodesic. The Weyl tensor differs from the Riemann curvature tensor in that it does not convey information on how the volume of the body changes, but rather only how the shape of the body is distorted by the tidal force. The Ricci curvature, or trace component of the Riemann tensor contains precisely the information about how volumes change in the presence of tidal forces, so the Weyl tensor is the traceless component of the Riemann tensor. This tensor has the same symmetries as the Riemann tensor, but satis

  • En géométrie riemannienne, le tenseur de Weyl, nommé en l'honneur d'Hermann Weyl, représente la partie du tenseur de Riemann ne possédant pas de trace. (fr)
  • 미분기하학에서 바일 곡률 텐서(Weyl曲率tensor, 영어: Weyl curvature tensor)는 리만 다양체의 곡률을 나타내는 완전 무대각합 (totally trace-free) 4-텐서장이다. 리만 곡률 텐서에서 리치 곡률 텐서에 해당하는 성분을 빼 없애고 남은 성분으로 생각할 수 있다. (ko)
  • Em geometria diferencial, o tensor da curvatura de Weyl, em homenagem a Hermann Weyl, é uma medida da curvatura do espaço-tempo ou, mais genericamente, uma variedade pseudo-Riemanniana. Como o tensor da curvatura de Riemann, o tensor de Weyl expressa a força de maré que um corpo sente quando se desloca ao longo de uma linha geodésica. (pt)
  • Тензор кривини Вейля — частина тензора кривини Рімана з нульовим слідом. Іншими словами, це тензор, що задовольняє всім властивостям симетрії тензора Рімана з додатковою умовою, що побудований за ним тензор Річчі дорівнює нулю. Названий на честь Германа Вейля. (uk)
  • Тензор кривизны Вейля — часть тензора кривизны Римана с нулевым следом. Другими словами, это тензор, удовлетворяющий всем свойствам симметрии тензора Римана с дополнительным условием, что построенный по нему тензор Риччи равен нулю. Назван в честь Германа Вейля. (ru)
  • Der Weyl-Tensor oder Weyl-Krümmungstensor ist ein Tensor 4. Stufe, der in der allgemeinen Relativitätstheorie (ART) die Rolle des Riemann-Krümmungstensor in den Feldgleichungen für den materiefreien Raum übernimmt (Vakuumlösungen). Er ist nach Hermann Weyl benannt. Der Weyl-Tensor ist in oder Dimensionen gleich Null. In vier und mehr Dimensionen ist er im Allgemeinen von Null verschieden. In Tensor-Notation ist der Weyl-Krümmungstensor: , und in der ART mit : . Dabei ist der metrische Tensor, der Ricci-Tensor und die Skalarkrümmung (sie entsteht durch Spurbildung aus dem Riccitensor).

  • In geometria differenziale, il tensore di curvatura di Weyl, che prende il nome da Hermann Weyl, è una misura della curvatura dello spaziotempo o, più in generale, una varietà pseudo-Riemanniana. Come il tensore di curvatura di Riemann, il tensore di Weyl esprime la forza mareale che un corpo avverte quando si muove lungo una geodetica. Il tensore di Weyl si differenzia dal tensore di curvatura di Riemann poiché non fornisce informazioni su come il volume del corpo cambi, ma piuttosto soltanto su come la forma del corpo sia distorta dalla forza mareale. È la curvatura di Ricci, o il componente traccia del tensore di Riemann, a contenere precisamente l'informazione su come i volumi cambino in presenza di forze mareali, quindi il tensore di Weyl è il componente a traccia nulla del tensore di (it)
