An apartness relation is a constructive strengthening, or positive formulation, of inequality. It is similar to the constructive distinction between nonempty (X ≠ ∅) and inhabited (∃ x ∈ X) sets. I will describe an apartness for continuous directed complete posets (domains) and explore its properties, focussing on intuitions and examples.
