Cámara和Haemers(2014)研究了删除某些边的完全图何时由其邻接谱(简称DAS)确定。对任意m≥ 6和n足够大的情况,从完全图Kn中去掉m条边,可以得到非DAS图.令G n表示从完全图K n删除六条边得到的所有图的集合。本文证明了G n中所有的图都是由它们的持久谱唯一决定的。然而,我们证明了对n≥ 7或n= 5,Gn中只有一对非同构的上谱图,而对n= 4或6,Gn中的所有图都是DAS.
Cámara and Haemers (2014) investigated when a complete graph with some edges deleted is determined by its adjacency spectrum (DAS for short). They claimed: for any m≥ 6 and every large enough n one can obtain graphs which are not DAS by removing m edges from a complete graph K n. Let G n denote the set of all graphs obtained from a complete graph K n by deleting six edges. In this paper, we show that all graphs in G n are uniquely determined by their permanental spectra. However, we show that for each n≥ 7 or n= 5 there is just one pair of nonisomorphic cospectral graphs in G n, and for n= 4 or 6 all graphs in G n are DAS.
