Traceless stress-energy and traversable wormholes
A. G. Agnese, M. La Camera
Abstract
A one-parameter family of static and spherically symmetric solutions to Einstein equations with a traceless energy-momentum tensor is found. When the nonzero parameter β lies in the open interval (0,1) one obtains traversable Lorentzian wormholes. One also obtains naked singularities when either β< 0 or β> 1 and the Schwarzschild black hole for β= 1.
