Özet
Let A be a unital algebra over a field of characteristic different from 2. The main goal of this work is to characterize higher commutators of A. In particular, we show that if H is a noncommutative higher commutator of A and contains the unity, then H is equal to either A or [A, A]. As a result, we prove that if there exist x, y is an element of A such that 1 = [x, y], then the only higher commutators of A are A and [A, A]. We also consider the structure of noncommutative Lie ideals of the form [U, A], where U is a Lie ideal of A, and show that if L = [U, A] is noncommutative and contains the unity, then L = [A, A] and [A, A] subset of U.(c) 2021 Published by Elsevier Inc.
