Derivations of the Lie algebra of strictly block upper triangular matrices

Abstract

Let $\mathcal{N}$ be the Lie algebra of all $n\times n$ strictly block upper triangular matrices over a field $\mathbb{F}$ relative to a given partition. In this paper, we give an explicit description of all derivations of $\mathcal{N}$.
