Let G be a connected and simple graph, and let i(G) denote the number of stable sets in G. In this letter, we have presented a sharp upper bound for the i(G)-value among the set of graphs with k cut edges for all possible values of k, and characterized the corresponding extremal graphs as well.
## Abstract The cyclic chromatic number of a plane graph __G__ is the smallest number Ο~__c__~(__G__) of colors that can be assigned to vertices of __G__ in such a way that whenever two distinct vertices are incident with a common face, they receive distinct colors. It was conjectured by Plummer an
