Abbreviation: CReg

A \emph{completely regular Hausdorff space} is a Hausdorff space $\mathbf{X}=\langle X,\Omega\rangle$ that is

\emph{completely regular}: $\ldots$

Remark: This is a template. If you know something about this class, click on the 'Edit text of this page' link at the bottom and fill out some information on this page.

It is not unusual to give several (equivalent) definitions. Ideally, one of the definitions would give an irredundant axiomatization that does not refer to other classes.

Let $\mathbf{A}$ and $\mathbf{B}$ be … . A morphism from $\mathbf{A}$ to $\mathbf{B}$ is a function $h:A\rightarrow B$ that is a homomorphism: $h(x \ldots y)=h(x) \ldots h(y)$

An \emph{…} is a structure $\mathbf{A}=\langle A,\ldots\rangle$ of type $\langle …\rangle$ such that

$\ldots$ is …: $axiom$

$\ldots$ is …: $axiom$
