Abstract
We review and elaborate on the issue of the dilaton transformation under the usual target space duality and its non-static generalization (or -model duality). It is found that the transformation law , which guarantees duality at the one-loop -model level should be modified at two (and higher) loop order. The non-static duality is illustrated on the example of cosmological solutions in with time-dependent radii of space torus.
