Welcome to the Subject Wikis Reference Guide. The subject wikis are run by Vipul Naik, and include wikis in many parts of mathematics (group theory, topology, commutative algebra, and many others). Quick links:
- A quick explanation for how the reference guide works -- more detailed help will be put up later.
- An explanation of what a subject wiki is
- The Subject Wikis Blog: A blog chronicling the development of subject wikis.
QUICK WORD: <random>Normal: This much overused word has several meanings in mathematics, and a few in physics, economics, chemistry and psychology. Too many think they're normal!@@@Simple: A much overused word for the straightforward, simple is also sometimes used for that which is too hard and difficult to break down.@@@Perfect: Too good to be true! You bet, except that the perfection sought by its definers in mathematics, physics, and economics often had different and extremely controversial ideas of what it means to be perfect.</random>

NOTE: The creation month need not coincide with the month of MediaWiki installation. In cases where the wiki was ported from elsewhere, the creation month may be earlier; in other cases, it may be later if the first edits happened long after installation.
Pageview count note: Estimates are based on Google Analytics data, not based on MediaWiki internal logs, which record about 2-3X the pageviews recorded by Google Analytics.
