Genus g graphs have pagenumber O( square root g)

Abstract

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/).<>
