AI 中文摘要
双扩张方法可用于从较小的二次李代数构造更大的二次李代数。本文利用该方法,在特征不为2的任意域上,描述了所有维数不超过7的可解不可分解二次李代数,尤其在代数闭域和实闭域上,得到了等距同构意义下的完整分类。
英文摘要
The double extension method allows the construction of quadratic Lie algebras from smaller ones. Using this approach, in this work we describe all solvable indecomposable quadratic Lie algebras of dimension at most $7$ over arbitrary fields of characteristic not $2$. In particular, we get complete classifications up to isometric isomorphism over algebraically and real closed fields.
