含非零主对角元的非powerful本原符号矩阵的基指数集

On the base set of primitive non-powerful sign pattern matrices with nonzero diagonal entries

  • 摘要: 研究了含非零主对角元的n阶非powerful本原 符号矩阵的基指数集, 得到了这类矩阵\\基指数的(最好)上界,并证明了它的基指数集不存在缺数段.

     

    Abstract: The base set for primitive non-powerful sign pattern matrices with nonzero diagonal entries is investigated, and the sharp upper bounds are obtained. It is shown that there exist no gaps in the base set of the classes of such matrices.
