WebFeb 15, 2024 · Define a closure operator on a complete lattice L as a function f: L → L which is order preserving and idempotent and satisfies x ≤ f x . Every closure operator arises from an adjunction between L and the lattice of closed elements (those x where f x = x ). The left adjoint takes x to its closure, f x. WebA closure operator on a set A is a function C: P ( A) → P ( A) satisfying following axioms: We call a set X ⊆ A closed (with respect to C) if C ( X) = X. To every closure operator C we may assign the set of all closed sets F ( C), which is a complete lattice.
