摘要

A book embedding of a graph G is a placement of its vertices along the spine of a book, and an assignment of its edges to the pages such that no two edges on the same page cross. The pagenumber of a graph is the minimum number of pages in which it can be embedded. Determining the pagenumber of a graph is NP-hard. A graph is said to be 1-planar if it can be drawn in the plane so that each edge is crossed at most once. The anthors prove that the pagenumber of 1-planar graphs is at most 10.
