The localisation of energy in general relativity

The energy localisation in the case of spherical symmetry advanced previously is justified in reference to an exact interior solution which is a generalisation of the rho = constant Schwarzschild solution. This reveals the inadequacy of the Tolman expression for localisation which also fails to provide the correct total mass for a system which exhibits certain discontinuities. A generalised localisation expression for arbitrary static systems is proposed for further consideration. (author)
