We present dynamic wormhole solutions in the framework of Lovelock gravity with compact extra dimensions. Calculations are done in D = 7, although they can be extended to an arbitrary number of extra dimensions. It is shown that as the wormhole inflates with the three-dimensional space, the extra dimensions deflate to very small, yet nonvanishing scales. The weak energy condition is shown to hold for certain ranges of the free parameters, everywhere, down to the throat of the wormhole. [ABSTRACT FROM AUTHOR]
