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: Simple: A much overused word for the straightforward, simple is also sometimes used for that which is too hard and difficult to break down.

Here is our list of subject wikis:

• Groupprops: The Group Properties Wiki (currently, around 2000 pages). Main topic is group theory
• Topospaces: The Topology Wiki (currently, around 400 pages). Main topics are point-set topology and algebraic topology
• Commalg: The Commutative Algebra Wiki (currently, around 300 pages). Main topic is commutative algebra, with some algebraic geometry.
• Diffgeom: The Differential Geometry Wiki
• Measure: The Measure Theory Wiki (to be set up)
• Noncommutative: The Noncommutative Algebra Wiki
• Companal: The Complex Analysis Wiki
• Cattheory: The Category Theory Wiki (just started)
• Market: The Economic Theory of Markets, Choices and Prices Wiki
• Number: The Number Theory Wiki
• Mech: The Classical Mechanics Wiki
• Galois: The Galois Theory Wiki

Some upcoming subject wikis:

• Linear: The Theoretical and Computational Linear Algebra Wiki
• Graph: The Graph Theory Wiki
• Complexity: The Complexity Theory Wiki
