| Popis: | The prime motivation behind this paper is to prove that any torus link $\mathcal{L}$ can be realized as the union of the one-dimensional connected components of the set of critical values of the argument map restricted to a complex algebraic plane curve. Moreover, given an isolated complex algebraic plane curve quasi-homogeneous singularity, we give an explicit topological and geometric description of the link $\mathcal{L}$ corresponding to this singularity. In other words, we realize this link as the union of the one-dimensional connected components of the set critical values of the argument map restricted to the intersection of the curve with a four-dimensional ball of a sufficiently small radius, centered at the given singularity. This established the first relationship between (co)amoebas and knot theory. Comment: 19 pages, 18 figures. arXiv admin note: text overlap with arXiv:0906.2729 |
