摘要：
A bounded linear operator A on a Banach space is called relatively regular, if there is a bounded linear operator B such that ABA = A. In this case B is called a g(1)-inverse of A. In this paper we characterize some classes of relatively regular operators A via the set {B-1 - B-2 : B-1 and B-2 are g(1)-inverses of A}. (C) 2008 Elsevier Inc. All rights reserved.
