Abstract
An operator S ∈ L (H) is said to be nearly equivalent to T if there exists an invertible operator V ∈ L (H) such that S*S = V−1T*TV. In this paper, we study several properties of nearly equivalent operators, and investigate their local spectral properties and invariant subspaces. © 2018, Element D.O.O.. All rights reserved.
