This category contains pages concerning Characterization of Compact Element in Complete Lattice:
Let $L = \struct{S, \preceq}$ be a complete lattice.
Let $a \in S$.
The following statements are equivalent::
- $(1)\quad a$ is a compact element
- $(2)\quad \forall I \subseteq S : I$ is an ideal $: a \preceq \sup I \implies a \in I$
- $(3)\quad \forall A \subseteq S : a \preceq \sup A \implies \exists F \subseteq A : F$ is finite $: a \preceq \sup F$
