Another representation for the maximal Lie algebra of \(\mathfrak{sl}(n+2,\mathbb R)\) in terms of operators
The authors give another short proof for the known fact that the Lie algebra of the second order \(n\)-dimensional vector equation \((y^a)''=0\), \(a=1,2,\ldots ,n\) is isomorphic to \({\mathfrak{s}}{\mathfrak{l}} (n+2,{\mathbb{R}})\).
