Peculiar anisotropic stationary spherically symmetric solution of Einstein equations

Motivated by studies on gravitational lenses, we present an exact solution of the field equations of general relativity, which is static and spherically symmetric, has no mass but has a nonvanishing spacelike components of the stressenergymomentum tensor. In spite of its strange nature, this solutio...
