| 概要 | An increasing sequence of integers is said to be universal for links if every link has a projection to the sphere such that the number of edges of each complementary face of the projection image comes from the given sequence. In this paper, we extend the concept of universal sequences to spatial graphs and prove that the sequence (2,3,4,5) is universal for spatial graphs without vertices of odd degree. |
