A: Show that the set of Hermitian matrices forms a real vector space

HanaHermitian matrices are $\textit{not}$ closed under complex scalar multiplication! For $H_n(\mathbb{C})$ (the set of all $n \times n$ Hermitian matrices) to form a $\textit{complex}$ vector space it must satisfy all the axioms of a vector space with the scalars being in the field $\mathbb{C}$. But...

1. Does the system allow Accepted but wrong Answers (s.g., math.stackexchange.com/a/529620/21813) to be deleted by the community? 2. When a Question eventually gets closed as a Duplicate, that auto-generated comment "Does this answer your question? <link to dupe target>" then becomes redundant; does the system then automatically delete that comment, or leave it alone?
1. I might be wrong, but I'm pretty sure that moderators are the only ones who can delete accepted answers.
2. The comment is automatically deleted.

1. As indicated in the [Privileges - Access 'trusted user' tools](https://math.stackexchange.com/help/privileges/trusted-user) help page, a privilege is allowing "Voting to delete answers with score of -1 or lower". Note this includes accepted answers, which I've participated in several times myself.
2. The comment is automatically deleted *only* if it wasn't edited. I often indicate I used approach0 in my duplicate comments, with those comments being left there after the quetion has been closed as a duplicate.

So, to be clear: 1. John's reply indicates that Accepted answers are not immune from community deletion. 2. That "does this answer your qstn" commment is subsequented AUTOMATICALLY deleted iff (1) it hasn't been manually edited and (2) the main/official close reason is Duplicate (as opposed to Lack of Clarity or whatnot). Hope I've understood correctly. Thanks

@bobeyt6 Another proof that AI was an invention of the devil.

mabye someone else can support my point of view here ? I think a question should be deteted after some time , if the author did not react and try to improve it. I just would like to know that I am not alone with this opinion.

Q: Can we understand zeta function behaviour on interval >1 because its without analytic continuation?can we determine where it intersects the real axis?

MenervaIs it possible to understand the behaviour of zeta function on the interval of numbers greater than one? If so can we determine where it intersects the real axis? Notice that on this interval no analytic continuation applied

@Feeds wasn't this question asked a couple of days ago?
claim here that $0.000\cdots 01$ with infinite many zeros is a valid decimal expansion ! It is of course not for the same reason that there is no day after eternity.

A user has asked three PSQs (one two three) in the past 16 hours, two of which got complete answers from the same high rep user :(
