Homotopy Types In Low-Dimensional Topology Seminar: From Framed Flow Categories To Spectra

Abstract/Media

After a reminder on framed flow categories and <n>-manifolds, I will describe and motivate a version of the Cohen-Jones-Segal construction, which constructs a spectrum or stable homotopy type out of a framed flow category. For example, for the framed flow category arising from Morse theory on a closed smooth manifold M, the construction gives the suspension spectrum of M with a disjoint basepoint added.
