Abstract
Let L be a finite-dimensional Lie algebra and I, J two ideals of L. Let \(\mathrm {Der}_J^I(L)\) denote the set of all derivations of L whose images are in I and send J to zero and let \(\mathrm {Der}^n_c(L)\) denote the set of all derivations \(\alpha \) of L for which \(\alpha (x)\in [x,L^n]\) for all \(x\in L\). In this paper, we have shown that if L and H are two n-isoclinic Lie algebras, then there exists an isomorphism from \(\mathrm {Der}^{L^{n+1}}_{Z_n(L)}(L)\) to \(\mathrm {Der}^{H^{n+1}}_{Z_n(H)}(H)\). Also, we give necessary and sufficient conditions under which \(\mathrm {Der}^n_c(L)\) is equal to a certain special subalgebra of the derivation algebra of L.
