李代数 Lie algebra

(重定向自Abelian Lie algebra)

数学上,李代数是一个代数结构,主要用于研究象李群和微分流形之类的几何对象。李代数因研究无穷小变换的概念而引入。“李代数”(以索菲斯·李命名)一词是由赫尔曼·外尔在1930年代引入的。在旧文献中,无穷小群指的就是李代数。

Lie algebra 李代数

(重定向自Abelian Lie algebra)

In mathematics, a Lie algebra (/l/, not /l/) is a vector space together with a non-associative multiplication called "Lie bracket" [x, y]. When an algebraic product is defined on the space, the Lie bracket is the commutator [x,y] = xy - yx.

Lie algebras were introduced to study the concept of infinitesimal transformations. Hermann Weyl introduced the term "Lie algebra" (after Sophus Lie) in the 1930s. In older texts, the name "infinitesimal group" is used.
