If you have a question about this talk, please contact Oscar Randal-Williams.

I will present classification results for 4-manifolds with boundary and infinite cyclic fundamental group, obtained in joint work with Anthony Conway and with Conway and Lisa Piccirillo. I will describe applications to knotted surfaces in simply connected 4-manifolds, and to investigating the difference between homotopy equivalence and stable homeomorphism. These applications will also draw on work with Patrick Orson and with Conway, Diarmuid Crowley, and Joerg Sixt.
