"In this paper, new exact solutions in eight-dimensional Lovelock theory will be presented. These solutions are the vacuum static wormhole, the black hole, and generalized Bertotti-Robinson space-times with nontrivial torsion," investigators in Valdivia, Chile report.
"All of the solutions have a cross product structure of the type M(5)x Sigma(3), where M-5 is a five-dimensional manifold and Sigma(3) a compact constant curvature manifold. The wormhole is the first example of a smooth vacuum static Lovelock wormhole which is neither Chern-Simons nor Born-Infeld. It will be also discussed how the presence of torsion affects the ''navigableness'' of the wormhole for ...
