Welcome

Tasks: start a new article • add basic, wanted or requested articles • add definitions • add metadata • edit new pages

Welcome to the Citizendium! We hope you will contribute boldly and well. Here are pointers for a quick start, and see Getting Started for other helpful "startup" links, our help system and CZ:Home for the top menu of community pages. You can test out editing in the sandbox if you'd like. If you need help to get going, the forum is one option. That's also where we discuss policy and proposals. You can ask any user or the editors for help, too. Just put a note on their "talk" page. Again, welcome and have fun!

You can find some more information about our collaboration groups if you follow this link CZ:Workgroups.You can always ask me on my talk page or others about how to proceed or any other question you might have.

Have fun and Happy editing!

Well, don't leave us hanging! Is this a reference to algebraic groups? algebraic groups over finite fields? Greg Woodhouse 14:22, 18 June 2007 (CDT)

Prime ideals

Dear Harald, thank you for your contributions, especially those to number theory. They are great. I came across your name because you added something to our article on prime numbers. Specifically, the following sentence intrigued me: "Algebraic integers factorize uniquely into prime ideals". Given your background, I'm sure you know what you're talking about, but I'd have thought that a prime ideal is a certain kind of ideal, thus a set, and it seems strange to factor a number in sets. I'm just mentioning it on the off-chance that you may have overlooked something.

Anyway, I hope that you'll continue to contribute. It would be great if you could finish the article on number theory. Unfortunately, I won't be able to help you with that — I haven't even done a single course on number theory. If you have any questions about the organization or the software though, I'll be happy to help. I'm also an editor in mathematics, meaning that I can approve articles, so please let me know if you're reasonably happy with an article. Incidentally, I had a short look at your home page and I'm sure that you will also become an editor if you apply for it. But above all, I hope you'll enjoy yourself here.

Best wishes,
