广义θ-图和广义梅花图φ的奇异性
Singularity of Generalized θ-Graphs and Generalized Plum Blossom φ-Graphs
摘要
Abstract
By using the method that the determinant of the adjacency matrix of the singular graph was equal to zero,we discussed the singularity of the generalized θ-graphs and the generalized plum blossom φ-graphs,and gave the necessary and sufficient conditions for the generalized θ-graphθ(a1,a2,…,ak)and the generalized plum blossom graph φ(a1,a2,…,ak)to be a singular graph,respectively.The probability values of singular graph occurring in these two types of graphs were calculated.关键词
