User talk:Julius

Welcome to ProofWiki! Since you're new, you may want to check out the general help page. It's the best first stop to see how things are done (next to reading proofs, of course!). Please feel free to contribute to whichever area of mathematics interests you, either by adding new proofs, or fixing up existing ones. If you have any questions please feel free to contact one of the administrators, or post your question on the questions page.

Here are some useful pages to help get you started:
 * Community Portal - To see what needs to be done, and keep up to date with the community.
 * Recent Changes - To keep up with what's new, and what's being added.
 * Check out our house style if you are keen on contributing.
 * Main Page talk - This is where most of the main discussions regarding the direction of the site take place. If you have any ideas, please share them!

House style
While your contributions are useful, you are encouraged to make an attempt to pick up on house style.

While I appreciate that you are already familiar with $\LaTeX$ and MediaWiki, and have developed your own coding style, it is different from the house style of presentation that we strongly adhere to on.

You may be able to perceive stylistic differences between the pages you are generating and those which already exist on the website.

It is also expected that every concept is linked internally to a definition page. The reason for this becomes obvious as you become familiar with our ultimate philosophy.

Please feel free to take advantage of this advice.

Many thanks in advance. --prime mover (talk) 09:01, 29 January 2017 (EST)


 * Thank you for the notification. Indeed I am aware of the differences. They arise partially from focusing on the volume of presented material regarding the target branch of mathematics first, to fulfil encyclopaedical aspect of this website. Coding differences come mostly from my own habits, and that will take some time to adjust. The presentation of material could be improved, and I am planning that as soon as the material by Gelfand has been covered. Most of divergence from the house rules come from the fact that I am trying to limit my time spent here (it's almost too easy too lose track of time while surfing and improving this website) while maximizing the volume of contribution. Another culprit are the proofs themselves. Due to brevity they are lacking some nonobvious steps, which still explanation, and the lack of these slightly demotivates proper phrasing as it is not clear how much adjustment a reasonable chunk of material will require. As for linking every concept I believe I am linking everything on the given page at least once, but I will check upon that. I will attempt to staying closer to the house rules, at least when it comes to coding. As for style of presentation, that probably will get improved by iterative reexamination.

What to do with Sturm-Liouville Problem?
Hey, I see you blanked the page Sturm-Liouville Problem. Was this as a reaction to someone's tyranny, or has the content been moved elsewhere?

If it has simply been removed, I propose to restore it and mark it with something like serious issues or rewrite. --barto (talk) (contribs) 15:56, 11 November 2017 (EST)


 * Currently, Sturm-Liouville Theory, which is not my page, contains the majority of results, which have to be formalised and presented within the House Rules. The contents of my page have been moved to Sturm-Liouville Problem/Unit Weight Function, since it is a special case of Sturm-Liouville Problem. The empty page was initially created to house the proof I had, but after noticing a more general description which was unfamiliar to me, I decided to give it a proper name. There was also a disagreement about the presentation (I am for making an unfinished article public vs the other party's presentation of appropriately formatted article), but that only shifted the time of actions. Fell free to fill or delete the empty page. --Julius (talk) 14:30, 18 November 2017 (EST)

More on house style
A quick request ... can you--prime mover (talk) 10:25, 13 January 2019 (EST) cut down on the number spaces that you put between every symbol? We aim for a happy medium between no spaces at all and everything separated by spaces. If you are using an automatic tool that generates the $\LaTeX$ for you, consider modifying its parameters. Inspect the source code of other pages for an example of how we like it here. It is tedious and wasteful of time changing all your pages into house style, and we would really not have to do it. Your cooperation is requested. --prime mover (talk) 17:15, 4 October 2018 (EDT)


 * No problem. I noticed an increased implementation of various shortcuts like "paren", "sqbrk", etc. which partially solves the problem. Could they be added to the list of "Common LaTeX Commands" below the editor? --Julius (talk) 04:17, 5 October 2018 (EDT)


 * That section is already big enough that it takes up a fair amount of real estate. Besides, the allowed formats for inserted code is limited in that it does not allow spaces to be included, which limits its usefulness: any code generated using more complex constructs than simple inclusion of $\LaTeX$ tags would need manual reformatting to start with. I'll experiment with different formats. --prime mover (talk) 05:01, 5 October 2018 (EDT)

Call for Deletion
Hi,

When you completely blank a page and move all its content into a new one, and then replace the original content with a Delete, please can you make sure that you first find all the pages that link to the new page and change everything that links to it? Otherwise we end up with loads of redlinks.

It is a better strategy to use the "Move" option to move pages around rather than create a new page and copy everything over, but I appreciate that you may not have the privileges to do that. In that case, rather than doing what you just did, can you instead invoke the rename template at the top of the page with an indication of what you think it ought to be renamed to?

Many thanks. --prime mover (talk) 10:24, 13 January 2019 (EST)


 * P.S. Can I rely on you to go ahead and change the links to the pages in question? Again, many thanks. --prime mover (talk) 10:24, 13 January 2019 (EST)


 * P.P.S. Right okay, I see you are already doing this. Cheers.


 * Sorry about that. There was some glitch in my thinking process. Actually I remember once having "Move" option, but that was over a year ago. Either way, I promise to use template you mentioned. --Julius (talk) 10:31, 13 January 2019 (EST)

I see you still prefer to use the write-new-page-and-delete option rather than the rename template technique on pages whose names you want to amend.

While it's okay and it works (as long as linked pages get renamed) it's suboptimal as you don't get any indication of the history.

Again, as I say, it would be better if you would use the rename template instead of deleting pages and recreating them as new pages, if that could be achieved.

thx --prime mover (talk) 07:07, 24 December 2020 (UTC)


 * No problem. Probably my exposure to outstanding to-be-renamed articles skewed my impression of how efficient this approach was. I wanted to make sure that I don't leave any bugs before I move to the next chapter, and, as the volume of material grows, I tend to forget what I did or planned to do. Anyway, I will adjust according to your advice. --Julius (talk) 20:30, 24 December 2020 (UTC)


 * Does not really matter how long it takes for a page to be renamed. We get round to them sooner or later. Problem is I don't get paid a salary for this. --prime mover (talk) 00:38, 25 December 2020 (UTC)

Source works
While the work you're doing on documenting every single source work on functional analysis ever written is applauded, we might want to step back a bit.

In particular, the instance of Book:Kösaku Yosida/Functional Analysis/Reprint of Sixth Edition.

IMO it's going a bit far to specify exact reprints of editions. The reason we started separating out editions into separate pages is because very frequently the works change significantly between editions. Different contributors may have access to different editions, and may be working a different citation thread. So to make sure that a citation is exact and accurate, we specify the edition so as to make sure it stays accurate.

However, as a reprint usually has exactly the same material as a new edition (although the pagination may change), it seems of little worth making a distinction between them. If contributor A has one printing and contributor B has a different printing (of the same edition) they will feel the need both to add their own copy, leading to two wiki pages exactly alike except for the printing.

So recommend we have just Book:Kösaku Yosida/Functional Analysis/Sixth Edition and date it to when it was actually first printed. --prime mover (talk) 18:12, 19 November 2019 (EST)


 * This was my attempt to test the ground on reprints, i.e. how to formulate the title and make links work and not deform their appearance. I am yet to attempt something similar with Shilov's case, where the reprint is partial, and is of the book with a different title. --17:57, 20 November 2019 (EST)

Enhanced editing rights
You will notice that you now have an enhanced set of rights. For some reason you had not been added to the "Trusted" group. That oversight has now been redressed.

This means that you should now have the ability to move and delete pages, along with other sundry powers.

Sorry this took so long to achieve, it is only just now that this had not been done. --prime mover (talk) 22:43, 10 January 2021 (UTC)


 * Thank you for trusting me. Probably this was due to certain disagreements we had some time ago. Anyway, being able to contribute is sufficient enough, and I don't think I will use new options that much, maybe with exception of "move". Thanks again. --Julius (talk) 04:47, 11 January 2021 (UTC)


 * We had a MediaWiki upgrade a while back where another level of user was added which by default did not have a whole bunch of more-or-less basic authorizations. Hence and so. --prime mover (talk) 06:20, 11 January 2021 (UTC)

Permanent links / redirects
A quick heads-up (something which I thought you'd pick up on at some stage):

When you are linking to a page with a forward slash in it, e.g. Definition:Derivative/Real Function, please always check to see if there is a non-slashed redirect, as in this case Definition:Derivative of Real Function.

We do it like this so as to make any subsequent refactoring easier. If we want to change the structure of the underlying pages (as we often seem to do) then all we need to do is change the target of the redirect within Definition:Derivative of Real Function, rather than have to go through every single page that link directly to Definition:Derivative/Real Function, which is tedious.

Thanks --prime mover (talk) 07:12, 9 March 2021 (UTC)


 * Incidentally, the link in question actually needed to be Definition:Derivative of Vector-Valued Function, or so I believe. --prime mover (talk) 07:15, 9 March 2021 (UTC)


 * No problem. Looking at functions as basis vectors is foreign to me, so some polishing may be needed.--Julius (talk) 07:50, 9 March 2021 (UTC)

Distributions
Good job, this is starting to take shape nicely. --prime mover (talk) 15:20, 2 April 2021 (UTC)


 * Conceptionally, not much more is left. Mostly trivial extensions of differential calculus and a few distributional ode's. But eventually, we'll have to tackle those definitions of Dirac function. This is not addressed in Sasane, but should be doable in principle.--Julius (talk) 15:57, 2 April 2021 (UTC)
