摘要: 利用度序列的概念, 证明变换图G--+与Hn--+同构, 当且仅当G与Hn同构. 以及在G连通的条件下,G--+与Cn--+同构,当且仅当G与Cn同构.Abstract: By the method of degree sequence, It was shown that G--+ is isomorphic to Hn--+ if and only if G is isomorphic to Hn. It was also shown that for a grap G, when G is connected, then G--+ and Cn--+ are isomorphic if and only if G and Cn are isomorphic.
