关于“k次幂等矩阵和矩阵的正交性”的注记

摘要

By applying the orthogonality of - potent matarices over field, this paper proves the relations among the algebraic equivalence, similarity and the equal characteristic polynomial over field are equivalent, then summarizes and generalizes the corresponding conclusions of JIN Hui- ping and WU Miao- xian.%应用数域上k次幂等矩阵和矩阵的正交性质，证明了在数域F上k次幂等矩阵的代数等价、相似和特征多项式相等这三者是等价的。概括和改进了金慧萍和吴妙仙《k次幂等矩阵和矩阵的正交性》的相应结论。
