| May 24, 2021 at 14:23 | comment | added | Jochen Glueck | @user31459: Hmm, I'm not sure I understand your question then. Could you clarifiy what you mean by "suffice if $T$ is bounded?" Which assumption in my post would you like to relax to boundedness? (Note that Nik Weaver's answer below already shows that this does not hold for gerenal bounded operators which are positive and unital.) | |

| May 24, 2021 at 14:16 | comment | added | Jochen Glueck | @user31459: Do you mean without a condition of the kind $T1 = 1$? This won't in general: just let $T$ be the multiplication with a non-negative continuous function $m$ that is $0$ at a certain point. | |
| May 24, 2021 at 13:58 | comment | added | user31459 | So will it suffice if T is bounded? | |

Corrected a few typos.
