Energy content of a slowly collapsing gravitating sphere

  • L. Herrera
  • N. O. Santos


We discuss in detail the differences between two different definitions of energy, within a slowly evolving distribution of fluid. The conspicuous role played by the Weyl and shear tensors and their relationship with the inhomogeneity and the anisotropy of the fluid are brought out.
