WebThe observation that topological models for first-order theories can expressed in the framework of locales appears, for instance, in Fourman and Grayson [6], where the analogy between points of a locale and models of a theory is emphasised; the identification of formal points with Henkin sets, gives a precise form to this analogy.

The definition of a Henkin Theory T requires that for each sentence ∃ x ϕ in the language of T there is a constant c ϕ such that T ⊢ ( ∃ x ϕ) ⇒ ϕ [ c / x]. I.e., ϕ is expected to have only the variable x free. It wouldn't work to extend this to formulas ϕ with other free variables. E.g., consider the following formula in the ...

The semantics of second-order logic establish the meaning of each sentence. Unlike first-order logic, which has only one standard semantics, there are two different semantics that are commonly used for second-order logic: standard semantics and Henkin semantics. In each of these semantics, the interpretations of the first-order quantifiers and the logical connectives are the same as in first-order logic. Only the ranges of quantifiers over second-order variables differ …
