Abstract
Suppose C is a bounded chain complex of finitely generated free modules over the Laurent polynomial ring L = R[x,x 1]. Then C is Rfinitely dominated, i.e. homotopy equivalent over R to a bounded chain complex of finitely generated projective Rmodules if and only if the two chain complexes C ? L R((x)) and C ? L R((x 1)) are acyclic, as has been proved by Ranicki (A. Ranicki, Finite domination and Novikov rings, Topology 34(3) (1995), 619–632). Here R((x)) = R[[x]][x 1] and R((x 1)) = R[[x 1]][x] are rings of the formal Laurent series, also known as Novikov rings. In this paper, we prove a generalisation of this criterion which allows us to detect finite domination of bounded below chain complexes of projective modules over Laurent rings in several indeterminates.
