DOI: 10.1140/epjc/s10052-020-08689-y
Abstract: Motivated by recent proposals of possible wormhole shape functions, we construct a wormhole shape function by employing the Karmarkar condition for static traversable wormhole geometry. The proposed shape function generates wormhole geometry that connects two… read more here.
