Links associated with generic immersions of graphs
arXiv:math/0409086 · doi:10.2140/agt.2004.4.571
Abstract
As an extension of the class of algebraic links, A'Campo, Gibson, and Ishikawa constructed links associated to immersed arcs and trees in a two-dimensional disk. By extending their arguments, we construct links associated to immersed graphs in a disk, and show that such links are quasipositive.
