Derivations of the Lie Algebra of Strictly Block Upper Triangular Matrices
Journal of Lie Theory, Volume 30 (2020) no. 4, pp. 1027-1046
\newcommand\Der{\operatorname{Der}} \newcommand\N{\mathcal N} Let $\N$ be the Lie algebra of all $n \times n$ strictly block upper triangular matrices over a field $\mathbb{F}$. Let $\Der(\N)$ be Lie algebra of all derivations of $\N$. In this paper, we describe the elements and the structure of $\Der(\N)$. We also determine the dimensions of component subalgebras of $\Der(\N)$.
