Moore-Penrose Inverses In Rings And Weighted Partial Isometries In C*-Algebras
APPLIED MATHEMATICS AND COMPUTATION(2021)
Abstract
We explore the existence of MP-inverse in rings with involution. In addition, we give some equivalent conditions for an element of a C*-algebra to be a weighted-EP element and weighted partial isometry. (C) 2020 Elsevier Inc. All rights reserved.
