Abstract:Let 𝔤 be an n-Lie superalgebra. We study the double derivation algebra [Formula: see text] and describe the relation between [Formula: see text] and the usual derivation Lie superalgebra Der(𝔤). We show that the set [Formula: see text] of all double derivations is a subalgebra of the general linear Lie superalgebra gl(𝔤) and the inner derivation algebra ad(𝔤) is an ideal of [Formula: see text]. We also show that if 𝔤 is a perfect n-Lie superalgebra with certain constraints on the base field, then the cent… Show more
“…It is obvious that the derivations of an n−Hom-Lie color algebra L are double derivations, and hence we have Der(L) ⊂ D(L). Note that there exists an n−Lie superalgebra L such that Der(L) = D(L) (see Remark 2.5 in [27]). Proof.…”

“…The main purpose of our work is to generalize the results of R. Bai, Y. Gao, Y. Zhang and Z. Li [7] and B. Sun, L. Chen and X. Zhou [27] to the case of multiplicative n−Hom-Lie color algebras. Double derivations are similar to the triple derivations of Lie algebras to some extent [33].…”
We study the double derivation algebra D(L) of n−Hom Lie color algebra L and describe the relation between D(L) and the usual derivation Hom-Lie color algebra Der(L). We prove that the inner derivation algebra Inn(L) is an ideal of the double derivation algebra D(L). We also show that if L is a perfect n−Hom Lie color algebra with certain constraints on the base field, then the centralizer of Inn(L) in D(L) is trivial. In addition, we obtain that for every centerless perfect n−Hom Lie color algebra L, the triple derivations of the derivation algebra Der(L) are exactly the derivations of Der(L).

“…Moreover, every derivation of the derivation algebra is an inner derivation. Double derivations of Lie superalgebras were introduced in [4], these derivations are similar to the triple derivations of Lie algebras to some extent in [7]. Zhao studied N-derivations of Lie algebras in [6].…”
The aim of this article is to discuss the n-derivation algebras of Lie color
algebras. It is proved that, if the base ring contains 1/n-1, L is a
perfect Lie color algebra with zero center, then every triple derivation of
L is a derivation, and every n-derivation of the derivation algebra nDer(L))
is an inner derivation.
