摘要 研究n阶单圈图补图的最大谱半径问题.证明了该问题的极图是(?),其中S_n^3是在3-圈的一个顶点上加n-3个悬挂点得到的图. This paper considered the following problem: Among all the complements of unicyclic graphs with order n, which one has the maximum spectral radius? It was showed that the extremal graph is Sn3, where Sn3 is obtained from a 3-cycle by attaching n - 3 pendant vertices to a vertex.
