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!

Hi there
Please excuse my rough handling of you out there today, but the proliferation of all this "this object is a group and therefore it's a semigroup and that means it's closed and to do that we demonstrate ..." Unless there's a really good reason for the detail, at the level we're working at, that level of detail gets in the way. None of the sources I've studied does that, but I understand it's a quick way in and all that.

Please feel free to add any missing justifications you like, on the grounds that some of them will stick, and some of them won't, and one that was too full of the result of insufficient proofreading before posting I'm afraid got reversed straight out.

In regards to analysis, please also be aware that we tend not to expressly raise the subject about which operator $1$ and $0$ are the identity of. By the time we're in analysis we know all that, let the fundamentalists and number theorists go work it out in their corner.

All the best. --prime mover (talk) 17:46, 25 May 2023 (UTC)


 * Incidentally I rarely use the UI to send a thank message, it's not we don't appreciate your work, just that the UI is clunky. --prime mover (talk) 17:49, 25 May 2023 (UTC)
