摘要：

Let D be a division ring and let M-n(D) be the ring of all n x n matrices over D with center Z, where n >= 2 is an integer. We describe the additive map f : M-n(D) -> M-n(D) such that f(x)x - xf(x) is an element of Z for all invertible (singular) x is an element of M-n(D). (C) 2013 Elsevier Inc. All rights reserved.
