Summary:

An oriented link is called $\mathbb{C}$ -boundary if it is realizable as $(\partial B,A\cap\partial B)$ , where $A$ is an algebraic curve in $\mathbb{C}^2$ and $B$ is an embedded $4$ -ball. This notion was introduced by Michel Boileau and Lee Rudolph in 1995. In a recent joint paper with N. G. Kruzhilin we gave a complete classification of $\mathbb{C}$ -boundaries with at most 5 crossings. In the present paper a more regular method of construction of $\mathbb{C}$ -boundaries is proposed and the classification is extended up to 6 crossings.
