Oct 25, 2021 at 22:05 | comment | added | Sam Hopkins | @Adam: again, it is considered inappropriate to delete a MO question after it has been answered (and anyways if you try you'll see you can't). In unusual/extreme cases you should get in contact with a moderator (which I am not, but Stefan Kohl mathoverflow.net/users/28104/stefan-kohl - who was also reverting your edits - is). | |
Oct 25, 2021 at 22:02 | comment | added | Adam | @SamHopkins : I want to delete it as I made a big mistake to ask the question; I am really regretful. Could you please delete it? | |

Your link 'here' was to edit your own post. I figured you probably wanted to link to the answer with a counterexample. Also, you use $A^{^*}$ A^{^*} for the adjoint; it should be $A^*$ A^* . I edited accordingly.
