| 概要 | The rigid isotopic classification of real curves of degree 6 with one real nondegenerate double point was done by Ilia Itenberg in 1992. He used the period domain for real K3 surfaces corresponding to real curves of degree 6 with one real nondegenerate double point. The rigid isotopy classes (up to projective equivalence) are in bijective correspondence with the connected components (considered up to equivalence) of a certain period domain which consists of a finite number of polytopes. In this paper we compensate the details of his interesting arguments. |
