One can associate a polymatroid with a hypergraph that naturally generalises the cycle matroid of a graph. Whitney's 2-isomorphism theorem characterises when two graphs have isomorphic cycle matroids. In this paper Whitney's theorem is generalised to hypergraphs and polymatroids by characterising wh
We show that all sets that are complete for NP under nonuniform AC 0 reductions are isomorphic under nonuniform AC 0 -computable isomorphisms. Furthermore, these sets remain NP-complete even under nonuniform NC 0 reductions. More generally, we show two theorems that hold for any complexity class C c
