Non-existence of symmetric biderivations on finite-dimensional perfect Lie algebras
Ignacio Bajo, Saïd Benayadi, Hassan Oubba
We show that there are no symmetric non-zero biderivations on perfect Lie algebras of finite dimension over a field of characteristic zero. We show that this is equivalent to show…
