Abstract |
|
Given two graphs G and H, a new graph G(H), called the composition (or lexicographic product) of G and H, can be formed. In this paper, a formula is developed to give the genus for a large class of lexicographic products. In the simplest special case, the genus of the product is given by the first Betti number of one of the factors. |
