| dbo:abstract |
El transport de Fermi–Walker és un procés en la relativitat general usat per definir un sistema de coordenades o un sistema de referència tal que tota la curvatura del sistema és deguda a la presència de massa o densitat d'energia i no deguda a una rotació arbitrària del sistema de referència. (ca) Fermi–Walker transport is a process in general relativity used to define a coordinate system or reference frame such that all curvature in the frame is due to the presence of mass/energy density and not to arbitrary spin or rotation of the frame.
