title = "SELF-INTERSECTIONS OF LAURENT POLYNOMIALS AND THE DENSITY OF JORDAN CURVES",
abstract = "We extend Quine{\textquoteright}s bound on the number of self-intersection of curves with polynomial parameterization to the case of Laurent polynomials. As an application, we show that circle embeddings are dense among all maps from a circle to a plane with respect to an integral norm.",
