Title: Static wormhole solution for higher-dimensional gravity in vacuum

Abstract

A static wormhole solution for gravity in vacuum is found for odd dimensions greater than four. In five dimensions the gravitational theory considered is described by the Einstein-Gauss-Bonnet action where the coupling of the quadratic term is fixed in terms of the cosmological constant. In higher dimensions d=2n+1, the theory corresponds to a particular case of the Lovelock action containing higher powers of the curvature, so that in general, it can be written as a Chern-Simons form for the AdS group. The wormhole connects two asymptotically locally AdS spacetimes each with a geometry at the boundary locally given by RxS{sup 1}xH{sub d-3}. Gravity pulls towards a fixed hypersurface located at some arbitrary proper distance parallel to the neck. The causal structure shows that both asymptotic regions are connected by light signals in a finite time. The Euclidean continuation of the wormhole is smooth independently of the Euclidean time period, and it can be seen as instanton with vanishing Euclidean action. The mass can also be obtained from a surface integral and it is shown to vanish.

  • Gravity in more than four dimensions may involve terms of higher order in the curvature, as well as the linear terms present in ordinary general relativity. I explore the ten-dimensional vacuum configuration M/sup 4/ x S/sup 6/. The ten-dimensional spherically symmetric potential is examined, and I determine conditions under which the formation of black holes is forbidden. Consequences for the stability of the vacuum are discussed.
  • We show that Schwarzschild geometry remains as a vacuum solution for those four-dimensional f(T) gravitational theories behaving as ultraviolet deformations of general relativity. In the gentler context of three-dimensional gravity, we also find that the infrared-deformed f(T) gravities, like the ones used to describe the late cosmic speed up of the Universe, have as the circularly symmetric vacuum solution a Deser-de Sitter or a Banados, Teitelboim and Zanelli-like spacetime with an effective cosmological constant depending on the infrared scale present in the function f(T).
  • A globally causal vacuum solution with the symmetries of the Goedel universe is obtained in the framework of higher-derivative gravity. This very peculiar and rare result has no similar one in standard general relativity. The Reboucas-Tiomno universe, i.e., the unique completely causal Goedel-type solution of Einstein's field equations with an algebraic Segre characteristic ((1,11)1), is shown to be a special case of our solution. We also show that our model is an embedding of the three-dimensional anti--de Sitter universe in four-dimensional space-time.
  • The field equations for a new theory of gravity are derived from a variational principle when electromagnetic fields are included in the Lagrangian density L. A static spherically symmetric solution to the field equations is obtained, which reduces to the Reissner-Nordstroem solution when a new gravitational coupling constant l equals zero. For l > m + (m/sup 2/ - 4..pi..Q/sup 2/)/sup 1/2/ black-hole event horizons are excluded from physical space-time.
  • The authors study how the curvature squared terms, which may be included in the gravitational action, affects cosmology. They show, in particular, that the resulting higher-derivative gravity theory in 5 space-time dimensions admits a unique Kasner-type solution which represents three static space dimensions and one expanding space dimension.
