Pt. 3 – Notions of equivalence & complexity for knotted surfaces | Dave Auckly, Kansas St U | PCMI
IAS | PCMI Park City Mathematics Institute
The presentation introduces standard tools in four-manifold topology, such as finger moves, Whitney moves, and boundary rolls, while employing dimensional reduction techniques with real analogs to visualize intersection patterns of surfaces. A central theme involves constructing exotic pairs of surf …
