Abstract

This paper constructs numerous examples of highly connected Poincar\'{e} complexes, each homotopy equivalent to a topological manifold yet not homotopy equivalent to any smooth manifold. Furthermore, we determine the homotopy type of any closed 2k2k-connected framed (4k+2)(4k+2)-manifold with Kervaire invariant one for k=7,15,31k=7,15,31.
