给定围长的单圈图的第二小斜能量

Fixed the Girth of Unicyclic Digraphs with the Second Minimal Skew Energy

图G→是n阶有向图,G→的斜邻接矩阵的特征值为λ1,λ2,···,λn.斜能量为εS(G→)=∑ni=1λi.在这篇文章中,给出了关于给定围长的单圈图的第二小斜能量.

Let G be an oriented graph of n order and λ1 ,λ2 ,… ,λn denote all the eigenvalues of the skew-adjacency matrix of G→. the skew energy εs G→= ∑n i = 1λi . In this article ,we will give a second minimal skew energy for fixed the girth of a graph.
