Definition
Let $\struct {S, \RR}$ be a relational structure.
Let $T \subseteq S$ be a subset of $S$.
An element $x \in T$ is a strictly minimal element (under $\RR$) of $T$ if and only if:
- $\forall y \in T: y \not \mathrel \RR x$
Also known as
This strictly minimal relation is often referred to as a minimal relation in some expositions of this subject.
The appellation strictly minimal has been coined by $\mathsf{Pr} \infty \mathsf{fWiki}$ so as to distinguish between this and the more mainstream concept of a minimal element which does not preclude $x \mathrel \RR x$.
