迹为整数的3×3阶正交矩阵的谱
Spectrum of 3×3 Orthogonal Matrices Whose Traces are Integers
摘要
Abstract
The relationship between eigenvalues and traces of 3×3 orthogonal matrices are discussed firstly,and the spectrums of 3×3 orthogonal matrices whose traces are integers are proved to be decided by traces and are illustrated by several examples. The main results provide a simple and practical method for the calculation of spectrum of 3×3 orthogonal matrices,which have wide applications.关键词
