摘要
以矩阵左半张量积为工具,研究了几种不同类型的线性映射的矩阵展开表示。作为特殊情况,给出了Lyapunov映射、辛映射、伴随映射、共轭映射的相关表示。最后给出了这种矩阵形式在李代数中的应用。
Using the left semi-tensor product of matrices as a tool,the matrix expansion representations of several different types of linear mappings are studied.As a special case,the related representations of Lyapunov mapping,symplectic mapping,adjoint mapping and conjugate mapping are given.Finally,the application of this matrix form in Lie algebra is given.
