Closed Expressions for Lie Algebra Invariants and Finite Transformations

R. Aldrovandi, A. L. Barbosa, L. P. Freitas

摘要:

给出了一个获得李代数不变量的完整封闭表达式的简单方法。不变量最终是群参数中的多项式。有限群元素的构造需要使用投影器,投影器的系数是不变多项式。给出了这些投影仪的详细的一般形式。封闭表达式有限洛伦兹变换,均质和非均质,以及伽利略变换,被发现作为例子。

英文摘要:

A simple procedure to obtain complete, closed expressions for Lie algebra invariants is presented. The invariants are ultimately polynomials in the group parameters. The construction of finite group elements require the use of projectors, whose coefficients are invariant polynomials. The detailed general forms of these projectors are given. Closed expressions for finite Lorentz transformations, both homogeneous and inhomogeneous, as well as for Galilei transformations, are found as examples.
