AI 中文摘要
本文研究了有限维幂零李超代数上的局部(反)超导子。首先,我们证明了在特征不为2的域$\mathbb{F}$上,每个有限维2步幂零李超代数都存在纯局部(反)超导子(即不是(反)超导子的局部(反)超导子)。然后,对于任意域上n>2的n步幂零李超代数,我们给出了保证纯局部(反)超导子存在的充分判据。此外,我们证明了3步幂零李超代数存在纯局部超导子。
英文摘要
In this paper, we study local superderivations and local anti-superderivations of finite-dimensional nilpotent Lie superalgebras over a field $\mathbb F$ with $\operatorname{char}\mathbb F\neq2$. First, we prove that every finite-dimensional two-step nilpotent Lie superalgebra admits pure local superderivations and pure local anti-superderivations (namely, local (anti-)superderivations that are not (anti-)superderivations). For nilpotent Lie superalgebras of nilpotency index greater than two, we establish sufficient conditions for the existence of pure local superderivations and pure local anti-superderivations. In particular, we prove that every three-step nilpotent Lie superalgebra admits a pure local superderivation.
