Wormhole-centered spacetimes in an n-dimensional expanding universe |
We study wormhole geometries in an n-dimensional expanding universe. The effect of various assumptions about the energy-momentum tensor on the existance of such solutions is examined and the validity or violation of energy conditions are discussed. The problem is formulated both in GR and extended theories of gravity, like the Brans-Dicke or f(R) gravities. |
