The real numbers can be defined synthetically as an ordered field satisfying some version of the completeness axiom.Different versions of this axiom are all equivalent in the sense that any ordered field that satisfies one form of completeness satisfies all of them, apart from Cauchy completeness and nested intervals theorem, which are strictly weaker in that there are non Archimedean fields ...
Semantic completeness is the converse of soundness for formal systems. A formal system is complete with respect to tautologousness or "semantically complete" when all its tautologies are theorems, whereas a formal system is "sound" when all theorems are tautologies (that is, they are semantically valid formulas: formulas that are true under every interpretation of the language of the system ...
Post gave a complete description of the lattice of all clones (sets of operations closed under composition and containing all projections) on the two-element set {T, F}, nowadays called Post's lattice, which implies the above result as a simple corollary: the five mentioned sets of connectives are exactly the maximal nontrivial clones.
A Complete Unknown was named one of the top 10 films of the year by the American Film Institute, and Chalamet is already a contender in the awards race for Best Actor (and is already up for a 2025 ...

If is a topological space and is a complete metric space, then the set (,) consisting of all continuous bounded functions : is a closed subspace of (,) and hence also complete. The Baire category theorem says that every complete metric space is a Baire space .
