Thin-shell wormholes supported by ordinary matter in Einstein--Gauss--Bonnet gravity

Abstract

The generalized Darmois--Israel formalism for Einstein--Gauss--Bonnet theory is applied to construct thin-shell Lorentzian wormholes with spherical symmetry. We calculate the energy localized on the shell, and we find that for certain values of the parameters wormholes could be supported by matter not violating the energy conditions.

Errors corrected, conclusion still valid for different values of the parameters. 8 pages, 3 figures
