完全二部图K_(a,b)的迭线图L^m(K_(a,b))的谱特征

Spectral Characterization of L^m(K_(a,b))

本文证明了当 (a,b) { (1,8) ,(2 ,4 ) ,(3,6 ) ,(4 ,4 ) ,(2 s2 - s,2 s2 +s) }时 ,Lm (Ka,b)以谱为特征 ,其中 a b,s 2 .

It is proved that L m(K a,b) is characterized by its spectra,when (a,b)｛(1,8),(2,4),(3,6),(4,4),(2s 2-s,2s 2+s)｝,where ab and s2.
