Template
Presents a standard text explaining the differences in terminology between the two main naming conventions for the Tychonoff separation axioms.

Usage

 *  

Note that the first parameter is "n" if the "alternative name" starts with a vowel, thereby requiring "a" to be "an". This is the case for "an Urysohn space" for example.

Similarly, The third parameter is "n" if "this name" starts with a vowel, thereby requiring "a" to be "an".

Variants of Name
From about 1970, treatments of this subject started to refer to this as a  space, and what is defined on as a  space as a  space.

The system as used here broadly follows.

The system used on the page at  differs from this.
