摘要
We study the star order on B(H) and show several properties for which the common star lower or star upper bound exists regarding the relationships among operators and projections. We give various characterizations of star order and obtain much simpler matrix representations with respect to star order relation. (C) 2015 Elsevier Inc. All rights reserved.
