Abstract
A closed range bounded operator on a Hilbert space is said to be an EP operator if the operator commutes with its Moore-Penrose inverse. In this paper, we characterize EP operators through factorization in the Krein space settings. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
