Biderivations, local and 2-local derivation and automorphism of simple $I ¨ $ -Lie algebras

Hassan Oubba

Given a finite-dimensional complex simple $I ¨ $ -Lie algebras over $C$ . We prove that every local , $2 -$ local derivation is a derivation and every local (resp.…

On conservative algebras of 2-dimensional Algebras

Hassan Oubba

In 1990 Kantor introduced the conservative algebra $W (n)$ of all algebras (i.e. bilinear maps) on the $n$ -dimensional vector space. In case $n > 1$ the algebra $\mathcal{W…
