Web9 ago 2024 · The Knaster–Tarski Fixpoint Theorem can act as a starting point to prove an important fixpoint theorem which asserts the existence of the least fixpoint of a monotonic self-mapping f on a CPO (formulated by Theorem 2.1 (4) in this note), so can the Bourbaki–Witt Theorem. CPO s are basic models of denotational semantics [ 5 ].
