论文摘要
我们研究了几乎可以使用矩阵铅笔的$ 2 $ 2 $ 2 $ 2 $ 2 $ 2 $ 2 $ 2 $ 2 $ 2 $ 2 $ 2 $的内部派生的内部派生。特别是，我们根据任意的代数封闭的特征，而不是$ 2 $和实际数字来确定此类代数的几乎所有内部派生。
We study almost inner derivations of $2$-step nilpotent Lie algebras of genus $2$, i.e., having a $2$-dimensional commutator ideal, using matrix pencils. In particular we determine all almost inner derivations of such algebras in terms of minimal indices and elementary divisors over an arbitrary algebraically closed field of characteristic not $2$ and over the real numbers.
