摘要
完全刻划出每行（或每列）至少有一个非零对称元且周期为２的ｎ阶不可约布尔矩阵所成的类 ＳＢ_ｎ，２＝｛Ａ∈ＩＢ_ｎ，２｜Ａ~２≥Ｉ_ｎ｝的幂敛指数集和最大密度指数集。
In this paper we make a research on a class of n order imperative irreducible Boolean matrix whose given period is 2 and every row or column has at least one nonzero symmetry entries, that is SB_n,2 = {A∈ IB_n,2 |A^2∈I_n}, and we completely characterize the exponential set of convergence and the ex ponential set of maximum density for the class of SB_n,2.
