## Abstract Several ways to separate a connected graph into three components by the removal of edges are discussed. Graphical parameters that count the number of edges removed are introduced and the relations between these parameters are given.
## Abstract Let __K(p, q), p โค q__, denote the complete bipartite graph in which the two partite sets consist of __p__ and __q__ vertices, respectively. In this paper, we prove that (1) the graph __K(p, q)__ is chromatically unique if __p__ โฅ 2; and (2) the graph __K(p, q)__ โ __e__ obtained by del
