Prepare to downvote me. But don't think of not downvoting me just because I pre-emptively self-deprecated myself to put a show of humility. Just pretend I'm as arrogant as I may be perceived to be in the questions below, you know, to be consistent.

Please help me improve. (Again consider this line arrogant.)

Question 1. What are possible reasons why

  1. this (Complexification of a map under nonstandard complexifications of vector spaces) closed with 3 downvotes

  2. this ($f$ is the complexification of a map if $f$ commutes with almost complex structure and standard conjugation. What if we had anti-commutation instead?) has 2 downvotes

  3. this ($f$ is the complexification of a map if $f$ commutes with structure $J$ and conjugation $\chi$. What is the relationship between $J$ and $\chi$?) is closed with a downvote


  1. this (Complexification of realification: Why compute eigenvalues?) has 5 upvotes

  2. this (https://stackoverflow.blog/2011/07/01/its-ok-to-ask-and-answer-your-own-questions/)


Basically I wanna ask and instead of having people reinvent the wheel, I wanna post my own thoughts, so they can comment on my thoughts instead of answering the question. If I post my own thoughts in the question post, then it may be too long for anyone to read. I think it's easier for everyone. Idk. Does it help if I make community wiki instead?

You may pretend that I'm asking arrogantly and not that I'm genuinely interested in improving my posts. Hell with new contributor. Not that I think I would sound humble or anything otherwise. Just in case.

Question 2. Have I made any statements about maths in the above posts that are incorrect?

    $\begingroup$ I think in terms of optics, making your self-answer community wiki is definitely a good idea (and in fact this is a custom at MO). Please note that MO is somewhat sui generis among SE sites, so that something that Jeff Atwood said once about asking and self-answering being encouraged doesn't necessarily play that well before an MO audience (although how it plays can be a function of tact and tone). $\endgroup$

    $\begingroup$ "instead of having people reinvent the wheel" <-- a large part of mathematics is thinking afresh about things that are "well-known". I would suggest, respectfully, that there might be people out there who have surprisingly informative and knowledgeable answers. If you do intend to answer your own question, why not wait a couple of days, and no signposting that you are going to do it? You might learn something. $\endgroup$ Nov 27, 2020 at 1:04
  • $\begingroup$ @DavidRoberts why doesn't anyone have a compilation of these good tips? thanks! anyhoo so what now? well i could do so for the future, but what does your comment mean for now? delete answer? make answer community wiki? $\endgroup$ Dec 3, 2020 at 23:33
  • $\begingroup$ @ToddTrimble thanks. what do you think of David Roberts' comment please? Update: done making community wiki on self-answers $\endgroup$ Dec 3, 2020 at 23:35
  • $\begingroup$ @ToddTrimble why don't we have jeff atwood or something make an update please? i mean it says 'To be crystal clear, it is not merely OK to ask and answer your own question, it is explicitly encouraged.' and 'never hesitate to ask and answer your own question on any Stack Exchange site.' --> come on $\endgroup$ Dec 3, 2020 at 23:39

    $\begingroup$ Another point worth considering is that the questions are all very similar and start off identically, or near-identically. This raises red flags immediately. The questions also start off by explicitly saying they are in relation to "studying" an introductory textbook, and also list a bunch of lecture notes. This puts the question very close to the boundary of what is on-topic, and given the repetitious nature some people will vote to close to reduce what they perceive as noise. I personally would leave the questions there as they contain possibly useful information, though they are closed. $\endgroup$ Dec 4, 2020 at 3:11

    $\begingroup$ " why don't we have jeff atwood or something make an update please?" See twitter.com/codinghorror/status/959297452233785346?lang=en for the chances of that. There are many things some very active people at MO would like, but that we can't get because of how we are currently part of the SE network. We can't call the shots for all the other communities, not least the core site of StackOverflow; even people at other SE sites sometimes have to just accept that SO is the biggest gorilla here. $\endgroup$ Dec 4, 2020 at 3:14

    $\begingroup$ I think all of David's comments are good. Another thing to keep in mind is that people here are busy and they want to get to the point as soon as possible. Your questions are close to being off-topic here, as David says, but making matters worse, they are -- I'm sorry -- lengthy and tedious. To answer your post: lengthy questions followed by lengthy thoughts on your question in self-answers are not going to attract people here. Quite the opposite. $\endgroup$
