Generalizing previous work, we study the collision of massless superstring plane waves in D space-time dimensions within an explicitly O(D - 2, D - 2)-invariant set of field equations. We discuss some general properties of the solutions, showing in particular that they always lead to the formation of a singularity in the future. Using the above symmetry, we obtain entire classes of new analytic solutions with non-trivial metric, dilaton and antisymmetric field, and discuss some of their properties of specific relevance to string cosmology.

Abstract
Generalizing previous work, we study the collision of massless superstring plane waves in D space-time dimensions within an explicitly O(D - 2, D - 2)-invariant set of field equations. We discuss some general properties of the solutions, showing in particular that they always lead to the formation of a singularity in the future. Using the above symmetry, we obtain entire classes of new analytic solutions with non-trivial metric, dilaton and antisymmetric field, and discuss some of their properties of specific relevance to string cosmology.File in questo prodotto:
