Solid angles and Seifert hypersurfaces
We show an explicit way to provide an explicit construction of a Seifert hypersurface for a codimension-2 link in R^{n+2}. The construction involves calculating solid angles of some surfaces. This reveals connections of our construction with magnetic potential studied already by Maxwell. This is a joint project with Supredee Dangskul (Edinburgh/Bangkok) and Andrew Ranicki (Edinburgh).
