Title: Braiding self-equivalences with bordism

Abstract:
Spaces of homotopy self-equivalences capture subtle geometric and 
homotopy-theoretic information about manifolds, but are often difficult 
to analyze directly. In this talk, I will present a framework that 
relates these spaces to bordism theories by organizing normal bundle 
data in a homotopy-theoretic way. For a closed smooth or topological 
manifold M of dimension at least four, we show that spaces of homotopy 
self-equivalences preserving prescribed normal information fit into a 
highly cartesian square involving infinite loop spaces representing 
certain bordism theories. This leads to braids of interlocking exact 
sequences connecting homotopy groups of self-equivalence spaces with 
bordism groups, providing a conceptual generalization of earlier work of 
Hambleton–Kreck on 4-manifolds. This is joint work with Ian Hambleton 
and Robin Sroka.
