there exists a unique ring homomorphism C̃ → S with V = U⊗C̃S. The ring C̃ is generated as an algebra by the entries of the matrices giving the universal complex with these Betti numbers, together with the universal Buchsbaum-Eisenbud multipliers assuring that the First Structure Theorem from [BE] holds. The generators of C̃ were described in [Hu]. Over a… (More)
