  2. Quantifier elimination - Wikipedia

    en.wikipedia.org/wiki/Quantifier_elimination

    Quantifier elimination is a concept of simplification used in mathematical logic, model theory, and theoretical computer science. Informally, a quantified statement " ∃ x {\displaystyle \exists x} such that … {\displaystyle \ldots } " can be viewed as a question "When is there an x {\displaystyle x} such that … {\displaystyle \ldots ...

  3. Elimination theory - Wikipedia

    en.wikipedia.org/wiki/Elimination_theory

    Quantifier elimination is a term used in mathematical logic to explain that, in some theories, every formula is equivalent to a formula without quantifier. This is the case of the theory of polynomials over an algebraically closed field , where elimination theory may be viewed as the theory of the methods to make quantifier elimination ...

  4. Quantifier (logic) - Wikipedia

    en.wikipedia.org/wiki/Quantifier_(logic)

    In logic, a quantifier is an operator that specifies how many individuals in the domain of discourse satisfy an open formula. For instance, the universal quantifier ∀ {\displaystyle \forall } in the first order formula ∀ x P ( x ) {\displaystyle \forall xP(x)} expresses that everything in the domain satisfies the property denoted by P ...

  5. Predicate functor logic - Wikipedia

    en.wikipedia.org/wiki/Predicate_functor_logic

    Eliminate y by prefixing the subformula with one instance of ∃. Repeat (1)-(6) until all quantified variables have been eliminated. Eliminate any disjunctions falling within the scope of a quantifier by invoking the equivalence:

    A quantifier that operates within a specific domain or set, as opposed to an unbounded or universal quantifier that applies to all elements of a particular type. branching quantifier A type of quantifier in formal logic that allows for the expression of dependencies between different quantified variables, representing more complex relationships ...

  8. Conservativity - Wikipedia

    en.wikipedia.org/wiki/Conservativity

    In formal semantics conservativity is a proposed linguistic universal which states that any determiner must obey the equivalence (,) (,).For instance, the English determiner "every" can be seen to be conservative by the equivalence of the following two sentences, schematized in generalized quantifier notation to the right.

  9. Truth-value semantics - Wikipedia

    en.wikipedia.org/wiki/Truth-value_semantics

    In formal semantics, truth-value semantics is an alternative to Tarskian semantics.It has been primarily championed by Ruth Barcan Marcus, [1] H. Leblanc, and J. Michael Dunn and Nuel Belnap. [2]
