A Contribution to the Fong-Tsui Conjecture Related to Self-adjoint Operators

Functional Analysis 2012-08-22 v1

Abstract

We are interested in an open question raised by Fong-Tsui (dating back to the beginning of the eighties of last century) as to whether a bounded operator whose absolute value is less than the absolute value of its real part is self-adjoint. The analogue in the unbounded operators setting is also treated.
