On action of outer derivations on nilpotent ideals of Lie algebras
Action of outer derivations on nilpotent ideals of Lie algebras are considered. It is shown that for a nilpotent ideal \(I\) of a Lie algebra \(L\) over a field \(F\) the ideal \(I+D(I)\) is nilpotent, provided that \(charF=0\) or \(I\) nilpotent of nilpotency class less than \(p-1\), where \(p=ch...

Algebra and Discrete Mathematics| Zusammenfassung: | Action of outer derivations on nilpotent ideals of Lie algebras are considered. It is shown that for a nilpotent ideal \(I\) of a Lie algebra \(L\) over a field \(F\) the ideal \(I+D(I)\) is nilpotent, provided that \(charF=0\) or \(I\) nilpotent of nilpotency class less than \(p-1\), where \(p=char F\). In particular, the sum \(N(L)\) of all nilpotent ideals of a Lie algebra \(L\) is a characteristic ideal, if \(charF=0\) or \(N(L)\) is nilpotent of class less than \(p-1\), where \(p=char F\). |
