设(G)是图G的Seidel矩阵。Seidel能量OfG，记为byes(G)，定义为Seidel矩阵S(G)OfG的所有特征值的绝对值之和。本文考虑了边删除对图的Seidel能量的影响。证明了≥ 9阶三部图T(n，3)的塞德尔能量总是随着边的删除而增加的。
LetS(G) be the Seidel matrix of a graphG. The Seidel energy ofG, denoted byES(G), is defined to be the sum of absolute values of all eigenvalues of the Seidel matrixS(G) ofG. In this paper, we consider the change of Seidel energy of graphs due to edge deletion. It is proved that the Seidel energy of the tripartite Turán graphT(n, 3) of ordern≥ 9 is always increased when an edge is deleted.
