# Exact Solutions of Einstein's Field Equations

@article{Negi2004ExactSO, title={Exact Solutions of Einstein's Field Equations}, author={Praveen Singh Negi}, journal={International Journal of Theoretical Physics}, year={2004}, volume={45}, pages={1684-1702} }

We examine various well known exact solutions available in the literature to investigate the recent criterion obtained in Negi and Durgapal [Gravitation and Cosmology7, 37 (2001)] which should be fulfilled by any static and spherically symmetric solution in the state of hydrostatic equilibrium. It is seen that this criterion is fulfilled only by (i) the regular solutions having a vanishing surface density together with pressure, and (ii) the singular solutions corresponding to a non-vanishing… Expand
