3-manifolds and 4-dimensional surgery

摘要

Let XX be a connected compact 3-manifold with non-empty boundary. Consider the boundary MM of X×D2X\times D^2. MM is a 4-dimensional closed manifold and has the same fundamental group as XX. Various examples of XX are known for which a certain assembly map A:H4(X;L)L4(π1(X))A:H_4(X;L)\to L_4(\pi_1(X)) is injective. For such an XX and any CW-spine BB of XX, there is a UV1UV^1-map p:MBp:M\to B. For any ϵ>0\epsilon>0, if the surgery obstruction for a TOP normal map (f,b):NM(f,b):N\to M vanishes, we can perform surgery on ff to change it into a p1(ϵ)p^{-1}(\epsilon)-controlled homotopy equivalence.
