用超广义线图构造整谱图

摘要

线图在图的谱理论研究中起着重要的作用.在本文中,通过研究超广义线图成为整谱图的充分条件,获得了一种全新的构造新的整谱图的方法,运用这种方法,可以构造出无穷多个新的整谱图.%Line graph plays an important role in spectral graph theory.In this article, we gain a new method by reaching on the sufficient conditions under which the super generlized line graph is the integral graph.And using this method we can construct infinite new integral graphs.
