Reverse Order Law for Closed Range Operators in Hilbert Spaces

Functional Analysis 2022-07-14 v1

Abstract

We present more than 50 results including some range inclusion results to characterize reverse order law for Moore-Penrose inverse of closed range Hilbert space operators. We use basic properties of Moore-Penrose inverse to prove the results. Some examples are also provided to illustrate failure cases to hold the reverse order law in infinite dimensional settings.
