摘要
探讨了轮与轮的联图的邻点被扩展和可区别全染色,并得到了它的邻点被扩展和可区别全色数,然后通过删边的方法分别得到了扇与轮的联图,扇与扇的联图的邻点被扩展和可区别全染色及它们的邻点被扩展和可区别全色数。
The neighbor expanded sum distinguishing total coloring of join of two wheels is discussed and its neighbor expanded sum distinguishing total coloring index is determined. Then the neighbor expanded sum distinguishing total colorings and neighbor expanded sum distinguishing total coloring indexes of joins of one fan and one wheel, and two fans are obtained, respectively by the method of deleting edges.
