We study the structure of the polynomial-time complete sets for NP and PSPACE under strong nondeterministic polynomial-time reductions (SNP-reductions). We show the following results. - If NP contains a p-random language, then all polynomial-time complete sets for PSPACE are SNP-isomorphic. - If NP PI co-NP contains a p-random language, then all polynomial-time complete sets for NP are SNP-isomorphic. © Springer-Verlag Berlin Heidelberg 2007.
