如果G是一个简单的连通图
A(G)是G的邻接矩阵
A(G)的特征值称为图G的特征值.如果对于G的任意的特征值λ
都有它的倒数1/λ也是G的一个特征值
则称图G具有互反性(R).更进一步
如果对于G的每一个特征值λ
都有λ和1/λ有相同的重数
则称图G具有强互反性(SR).有(SR)性质的树已经被完全刻画了.有(SR)性质的单圈图在理论上被刻画了.本文研究具有(SR)性质的双圈图.得到了一类双圈图具有(SR)性质的一个充要条件
并由此给出了这类双圈图具有(SR)性质的一个无穷类.
We consider only simple connected graph.It is said that a graph has property(R)
if G is nonsingular and the reciprocal of each of its eigenvalue is also an eigenvalue of G.Further
if the multiplicity of each eigenvalue equals that of its reciprocal
the graph is said to have property(SR).The tree with property(SR) have been characterized completely. The unicyclic graphs have been characterized in theory.In this paper
the properties of bicyclic graphs with property(SR) is studied.We obtain a necessary and sufficient condition for a class bicyclic graphs with property(SR)
and thus give an infinite class of such bicyclic graphs with property(SR).
