The 12 pages that link to Domain of discourse, each with the reason it gives.

• First-order logicRelated: The domain fixes which objects first-order variables can refer to.

• Predicate logicRelated: A formula's domain determines which objects its quantified claims cover.

• CounterexampleRelated: A case is a counterexample only if it belongs to the claim's stated domain.

• Interpretation (logic)Related: An interpretation must specify which objects its variables range over.

• QuantifierRelated: A quantifier’s range depends on which objects the domain contains.

• Existential quantificationRelated: The domain determines which objects can witness an existential claim.

• Universal quantificationRelated: Changing the domain can change whether a universal statement is true.

• Set-builder notationRelated: The domain clarifies which objects the defining condition considers.

• PredicateRelated: A domain determines which objects a predicate can apply to.

• Structure (mathematical logic)Related: The domain supplies the objects on which this structure’s symbols are interpreted.

• Existence theoremRelated: Existence depends on which objects the theorem permits as candidates.

• Universe (mathematics and logic)Related: In first-order logic, this is the universe that fixes the possible values of variables.
