For a manifold M, the structure set S…M; rel q† is the collection of manifolds homotopy equivalent to M relative to the boundary. Siebenmann [11] showed that in the topological category, the structure set is 4-periodic in the sense that S…M; rel q†GS…M D; rel q† up to a copy of Z. The periodicity has been extended in [27] to topological manifolds with… CONTINUE READING
