Abstract

Beben and Wu showed that if MM is a (2n2)(2n-2)-connected (4n1)(4n-1)-dimensional Poincar\'{e} Duality complex such that n3n\geq 3 and H2n(M;Z)H^{2n}(M;\mathbb{Z}) consists only of odd torsion, then ΩM\Omega M can be decomposed up to homotopy as a product of simpler, well studied spaces. We use a result from \cite{BT2} to greatly simplify and enhance Beben and Wu's work and to extend it in various directions.
