Jun 24, 2024 · FABIAN HEBESTREIT, MARKUS LAND, MICHAEL WEISS, AND CHRISTOPH WINGES Abstract. We construct a Poincar´e complex whose periodic total surgery obstruction van-ishes but whose Spivak normal fibration does not admit a reduction to a stable euclidean bundle. This contradicts the conjunction of two claims in the literature: Namely, on the one
