== What is this project about ==
Hundreds or even thousands of properties of rings were studied within Ring Theory. Sometimes it is known that every ring with properties A,and B,has property C is D as well; sometimes the problem is still open; and very often, it was settled down long ago by a clever counterexample which is only known to a handful of experts.
The main goal of this project is to collect non-trivial examples and present them in a way that is reasonably-easy to search manner.
== How do I join? ==
Contributing is simple:
# Open To create an account , go to the main page, and [http://xi.math-wiki.com/ log-in through a gmail account] (is it currently impossible to choose your login-name; it will be set-up by the interaction of this website with gmail).# To log-in after you have an account, press the link at the upper-left corner## (login = "כניסה לחשבון").# Once you have an account, you can change the interface language by going to Preferences; the second section in the first tab.## (Preferences = "העדפות").# Start working ## (edit any page by pressing = "עריכה")
The website has some (though limited) TeX support. The code <nowiki><math>M_n(F[x])</math></nowiki> will display <math>M_n(F[x])</math>, etc.
== About the website ==
The project runs on a Wiki-line like platform, currently hosted on "math-wiki", which was created by Erez Scheiner, mostly for the students at the mathematics department at Bar Ilan University. Hence the Hebrew user interface and some awkward left-to-right issues.
At some point we'll move to our own server.
== What goes where ==
The project has two main parts:
* '''Examples'''. Examples should be precisely described. If the details are not easy to verify, please include a reference to the literature. The material will be organized into chapters and sections as it accumulates.
* '''Queries'''. Is every finitely generated nil algebra necessarily nilpotent? If there are examples you think the project should cover, list them here.
