User talk:John Coupe

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!

sources

Don't worry too much about sources. If you have one, and / or have used it directly to provide the material, then post it up. If not, then it is not important.

The only place where we are concerned about sources is in definitions. We get tugged astray a while back by some definitions consisting of material which was not backed up by sources, which was subtly different from actual published sources which could be confirmed. Differences in definitions can mean the difference between a proof based on such definitions being valid and not being valid.

If we do find sources which offer different definitions (that is, defs which are not logically equivalent) for certain concepts, we ensure to make a specific note about it and a warning as to what the differences are. --prime mover (talk) 18:01, 28 December 2019 (EST)
