团覆盖宽度和团和

Clique Cover Width and Clique Sum

Farhad Shahrokhi

摘要:

对于无向图$G$中的团覆盖$C$,$C$的团覆盖图是通过将$C$中的每个团的顶点收缩为单个顶点而获得的图。G的团覆盖宽度,记为$CCW(G)$,是$G$的所有团覆盖图的带宽的最小值。当$G$是$G_1$与$G_2$的团和时,我们证明了$CCW(G) \le 3/2(CCW(G_1) + CCW(G_2))$ .

英文摘要:

For a clique cover $C$ in the undirected graph $G$, the clique cover graph of $C$ is the graph obtained by contracting the vertices of each clique in $C$ into a single vertex. The clique cover width of G, denoted by $CCW(G)$, is the minimum value of the bandwidth of all clique cover graphs of $G$. When $G$ is the clique sum of $G_1$ and $G_2$, we prove that $CCW(G) \le 3/2(CCW(G_1) + CCW(G_2))$.
