Abstract:We prove that each local Lie n-derivation is a Lie n-derivation under mild assumptions on the unital algebras with a nontrivial idempotent. As applications, we obtain descriptions of local Lie n-derivations on generalized matrix algebras, triangular algebras, nest algebras, von Neumann algebras, and the algebras of locally measurable operators affiliated with a von Neumann algebra.
“…Later, Chen and Lu [3] proved that each local Lie derivation of nest algebras on Hilbert spaces is a Lie derivation. In [14,15], Liu and Zhang proved that the same is true for local Lie derivations on von Neumann algebras and a certain class of triangular algebras, respectively. The purpose of the present paper is to characterize local Lie derivations of generalized matrix algebras under certain conditions.…”

Let G be a generalized matrix algebra. We prove that, under certain conditions, every local Lie derivation δ of G can be written in the form δ = d + h, where d is a derivation of G and h is a linear map from G into Z(G) vanishing on each commutator. The result is then applied to some full matrix algebras and triangular algebras.

“…[13,Theorem 7.5]). Based on these results, many authors have studied local derivations on operator algebras, for example, see in [2,3,4,5,6,7,8,9,10,11,12,15,16,17,18,19,20,22,23].…”
In the present paper we prove that every additive (not necessarily homogenous) local inner derivation on the algebra of matrices over an arbitrary field is an inner derivation, and every local inner derivation on the ring of matrices over a finite ring generated by the identity element or the ring of integers is an inner derivation. We also prove that every additive local inner derivation on the Jordan algebra of symmetric matrices over an arbitrary field is a derivation, and every local inner derivation on the Jordan ring of symmetric matrices over a finite ring generated by the identity element or the ring of integers is a derivation.

Let A be a unital associative algebra and M be an A-bimodule. A linear mappingand ϕ is called a local Lie derivation if for every A in A, there exists a Lie derivation ϕ A (depending on A) from A into M such that ϕ(A) = ϕ A (A). In this paper, we prove that every local Lie derivation on von Neumann algebras is a Lie derivation; and we show that if M is a type I von Neumann algebra with atomic lattice of projections, then every local Lie derivation on LS(M) is a Lie derivation.
