摘要
A two-dimensional integral identity is derived for a genera) asymptotically flat four-dimensional spacetime, providing a generalization of the 'virial' identity obtained by Bonazzola for the stationary axisymmetric case. It is applied to show that some spatial component of the stress-energy tensor must be positive in some (if not all) points of a static stellar model. This identity has also proved to be useful for checking numerical solutions of Einstein's equation describing rotating neutron stars.
