一类含有2n个非零元的极小谱任意符号模式

摘要

Gave a new class of minimally spectrally arbitrary patterns with 2n nonzero entries.The sign pattern has been proved to be minimally spectrally arbitrary by using nilpotent-Jacobian method and nilpotent-centralizer method.%给出了一类新的含有2n个非零元的极小谱任意符号模式矩阵，并运用幂零-雅可比方法和幂零-中心化方法证明该符号模式是谱任意的。
