摘要

图的图书嵌入包括沿书脊的顶点的线性排序和对页的边的分配，以便同一页上的边不相交。图可以嵌入的最小页数是它的页码。得到如下结果:(1)g属的任意图的页数为0(平方根g);(2)大多数n顶点d正则图的页数为Omega(√dn/sup 1/2-1/d/)。

Genus g graphs have pagenumber O( square root g)

A book embedding of a graph consists of a linear ordering of the vertices along the spine of a book and an assignment of edges to pages so that edges on the same page do not intersect. The minimum number of pages in which a graph can be embedded is its pagenumber. The following results are presented: (1) any graph of genus g has pagenumber O( square root g); and (2) most n-vertex d-regular graphs have pagenumber Omega ( square root dn/sup 1/2-1/d/).<>
