Almost inner derivations of finite-dimensional simple Leibniz algebras

UDC 512.5 We study almost inner derivations of finite-dimensional simple Leibniz algebras. First, we examine almost inner derivations of the simple Leibniz algebra $\mathfrak{sl}_2\ltimes\mathcal{I}$  and prove that every  derivation of this kind is inner. Furthermore, we analyze almost inner deriva...
