✦ Synopsis
Mahaney's Theorem states that there are no sparse NP-complete problems if P # NP. We propose an adaptation of that theorem to the Blum-Shub-Smale model of computation of the reals with addition and equality. In that setting, sparseness is defined in terms of topological dimension instead of cardinality. @ 1997 Elsevier Science B.V.

It is shown that the G-dimension and the complete intersection dimension are relative projective dimensions. Relative Auslander-Buchsbaum formulas are discussed. New cohomology theories, called complexity cohomology, are constructed. The new theories play the same role in identifying rings (and modu
