## Abstract Examples are given to show that the nonorientable genus of a graph is not additive over its blocks. A nonorientable analog for the Battle, Harary, Kodama, and Youngs Theorem is proved; this completely determines the nonorientable genus of a graph in terms of its blocks. It is also shown

In this paper, we obtain a relation between the spectral radius and the genus of a graph. In particular, we give upper bounds on the spectral radius of graphs with \(n\) vertices and small genus. " " 1995 Academic Press. Ins

## Abstract The cochromatic number of a graph __G__, denoted by __z__(__G__), is the minimum number of subsets into which the vertex set of __G__ can be partitioned so that each sbuset induces an empty or a complete subgraph of __G__. In this paper we introduce the problem of determining for a surf

In this article new genus results for the tensor product H @ G are presented. The second factor G in H @ G is a Cayley graph. The imbedding technique used to establish these results combines surgery and voltage graph theory. This technique was first used by A. T. White [171. This imbedding technique

We prove that the following problem is NP-complete: Given a cubic graph G and a natural number g, is it possible to draw G on the sphere with g handles added?
