Abstract
Inhomogeneous multidimensional cosmological models with a higher-dimen sional space-time manifold M = M(0) X Pi(i=1)(n)M(i) (n greater than o r equal to 1) are investigated under dimensional reduction to tensor-m ultiscalar theories. In the Einstein conformal frame, these theories t ake the shape of a flat sigma model. For the singular case where M(0) is two dimensional, the dimensional reduction to dilaton gravity is pr eformed with different distinguished representations of the action.
