    Abstract:

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