For questions about number fields that are totally real, i.e. whose every complex embedding has real image.

For questions related to the Néron model (or Néron minimal model, or minimal model). The Néron model for an abelian variety $A_K$ defined over the field of fractions $K$ of a Dedekind domain $R$ is the "push-forward" of $A_K$ from $\text{Spec}(K)$ to $\text{Spec}(R)$.

Relevance logics, also called relevant logics, are non-classical logics developed as attempts to avoid the paradoxes of material and strict implication.

For questions related to profunctors. If $C$ and $D$ are categories, then a profunctor from $C$ to $D$ is a functor of the form $H^F:D^{op}×C→\text{Set}$.

Apt for questions related to perfect map which is a particular kind of continuous function between topological spaces that are weaker than homeomorphisms, but strong enough to preserve some topological properties such as local compactness that are not always preserved by continuous maps.

A complete group is a centerless group that has only inner automorphisms ($\textrm{Aut}(G) = \textrm{Inn}(G)$). Equivalently a centerless group is complete iff $\textrm{Aut}(G)$ is isomorphic to $G$. To be used with the tag [group-theory].
