Tricyclic graphs with exactly two main eigenvalues

He Huang, Hanyuan Deng

摘要:

图$G$的特征值称为主特征值,如果它有一个特征向量的元素之和不等于零。本文确定了所有具有恰好两个主特征值的连通三圈图。

英文摘要:

An eigenvalue of a graph $G$ is called a main eigenvalue if it has an eigenvector the sum of whose entries is not equal to zero. In this paper, all connected tricyclic graphs with exactly two main eigenvalues are determined.
