Definition:Smallest/Ordered Set/Subset

Definition
Let $\struct {S, \preceq}$ be an ordered set.

Let $T \subseteq S$ be a subset of $S$.

An element $x \in T$ is the smallest element of $T$ :


 * $\forall y \in T: x \preceq \restriction_T y$

where $\preceq \restriction_T$ denotes the restriction of $\preceq$ to $T$.
