General class of vacuum Brans-Dicke wormholes

F. S. N. Lobo, M. A. Oliveira

Recently, traversable wormhole geometries were constructed in the context of f(R) gravity. The latter is equivalent to a Brans-Dicke theory with a coupling parameter omega=0, which is apparently excluded from the narrow interval, -3/2

Exact: solutions - Modified: theories: of: gravity
