Title: Loops on a punctured disk, and knotted tubes in R^4


Classically, knots are one-dimensional strings knotted in three-dimesional space. In this talk we'll discuss two very different flavours ganeralised knot theory: one higher dimensional, one "very low dimensional". We'll end with a mystery: there is a correspondence between certain invariants of these two different knot theories, which must be rooted in a relationship between their topologies - and we don't understand how.
