幂零-雅可比方法的一个应用

An application of Nilpotent-Jacobian method

为丰富谱任意符号模式矩阵类,本文给出了两个新的含有3n个非零元的复符号模式矩阵,运用中值定理来实现幂零,并扩展了幂零-雅可比方法,证明了两个复符号模式矩阵是极小谱任意的。

To enrich the spectralty arbitrary pattern matrix class, we present two new complex sign pattern matrix with nonzero entries. We implement nilpotent with intermediate value theorem. We also extend Nilpotent-Jacobian method and 3n prove two complex sign pattern matrix are minimally spectrally arbitrary.
