Some examples of EP operators

Abstract

We give some examples of EP and non-EP operators to show that the main results of Mohammadzadeh Karizakia {\it et al} [Some results about EP modular operators, {\it Linear and Multilinear Algebra}, DOI: 10.1080/03081087.2020.1844613] are not correct even in the case of Hilbert spaces.
