Complements of connected hypersurfaces in S4S4

    Let XX and YY be the complementary regions of a closed hypersurface MM in S4=XMYS4=XMY. We use the Massey product structure in H(M;) to limit the possibilities for χ(X) and χ(Y). We show also that if π1(X)1 then it may be modified by a 2-knot satellite construction, while if χ(X)1 and π1(X) is abelian then β1(M)4 or β1(M)=6. Finally we use TOP surgery to propose a characterization of the simplest embeddings of F×S1.
