CanadaAbstract:
I will outline the construction of numerical invariants of embedded webs based on Heegaard Floer homology. This is motivated by some questions regarding the four-dimensional topology of strongly invertible knots, embedded theta-shaped graphs, and linking number zero two-component links. I will discuss said questions in the first part of the talk.
