摘要
定义了恰有2个顶点度大于2的树为似双星树,分析了似双星树最大Laplacian特征值,并结合其线图的性质,证明了似双星树由它的Laplacian谱确定.
A tree is called a double starlike tree if it has exactly two vertices of degree greater than two. The maximum Laplaeian eigenvalues of a double starlike is analyzed, and combined with the character of a linear graph. Aouble starlike is proved to be determined by their Laplaeian spectra.
