Subwiki:Fact article

Each subject wiki has certain kinds of articles called fact articles. These articles state a known or established fact. Further sections in the article are highly variable and depend both on the nature and organization of the subject wiki, and the nature of the specific fact.

Article-tagging templates

There are boxes at the top of many fact articles on subject wikis. Each such box is generated by an article-tagging template.

Sections of the fact article

Statement

Further information: Subwiki:Statement section in fact articles

This is a mandatory section. It clearly states the fact, possibly in many different formats (for instance, with symbols, and without symbols). The goal of this section is that people who simply want to know the fact should be satisfied with reading the Statement section.

Related facts

This is an optional section, giving other facts closely related to the given fact. The relation may be in form of statement, method of proof, or nature of implications.

Definitions used

This is an optional section, giving the (relevantly chosen) definitions of terms used in the statement of the fact. All definitions of these terms need not be given; the definitions that are most directly pertinent to the statement should be provided.

Facts used

This is an optional section, listing those facts that are used in the proof or demonstration of truth of the given fact.

Applications

This section gives a brief description of how and where the fact is applied.

Proof

Further information: Subwiki:Proof

This section gives the proof. The format of the proof may depend on the precise subject wiki, though there are general recommended guidelines.
