For a 3-connected graph with radius r containing n vertices, in [1] r < n/4 + O(log n) was proved and r < n/4 + const was conjectured. Here we prove r < n/4 + 8. Let G be a simple 3-connected finite graph on n vertices with vertex set V(G) and edge set E(G). For X, YE V(G) we denote by d(X, Y) the

## 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
We show that an n-vertex bipartite K 3,3 -free graph with n 3 has at most 2n -4 edges and that an n-vertex bipartite K 5 -free graph with n 5 has at most 3n -9 edges. These bounds are also tight. We then use the bound on the number of edges in a K 3,3 -free graph to extend two known NC algorithms fo
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.
