非二部图上Laplace算子的特征值

Eigenvalues of Laplace operators on non-bipartite graphs

Hongjun Wang, Hongmei Song, Jia Zhao

摘要:

本文研究了非二部图上Laplace算子在标准条件和反标准条件下的特征值的比较。首先,我们给出了任意边长的等边度量图上Laplace算子特征值的计算。在此基础上,利用余弦函数和反余弦函数的性质,比较了在等边非二部图上Laplace算子的标准条件和反标准条件下的特征值.此外,我们还给出了一类特殊的不等边非二部图的标准特征值与反标准特征值之间的不等式。

英文摘要:

This paper considers the comparison between the eigenvalues of Laplace operators with the standard conditions and the anti-standard conditions on non-bipartite graphs which are equilateral or inequilateral. First of all, we show the calculation of the eigenvalues of Laplace operators on equilateral metric graphs with arbitrary edge length. Based on this method, we use the properties of the cosine function and the arccosine function to find the comparison between the eigenvalues of Laplace operators with the standard conditions and the anti-standard conditions on equilateral non-bipartite graphs. In addition, we give the inequalities between standard and anti-standard eigenvalues on a special inequilateral non-bipartite graph.
