Scientific paper

Mechanisms for the preferential expansion of three of the spatial dimensions of a ten-dimensional universe are considered, in the context of the ten-dimensional supertring derived field theory with the gravitational field, the dilaton field and the three-index tensor field H. Two models in which the H field defines spatial three-spaces are investigated. One is quasi-chaotic at early times and leads to uniform expansion of all dimensions at later times; the other gives preferential expansion of one three-space. One possibility for the transition to the observed universe, through particle production by the dilaton field, is studied.
