| Abstract: | The Narumi-Katayama index of a graph G, denoted by NK(G), is equal to the product of the degrees of the vertices of G. For various classes of graphs, we characterize the graphs G for which NK(G) assumes an extremal (minimal or maximal) value. © 2011 Elsevier Ltd. All rights reserved. |
