摘要
通过研究星图Sn+1的两类组合图之并的伴随多项式的因式分解,证明了这类并图的补图的色等价性。
The chromatic equivalent character on the complement graph in the concurrent graph of two types of combination graphs is proved in this paper through the study of the adjoint polynomial facterization in the concurrent graph of two types of combination graphs on the star graph Sn ＋ 1.
