The proof formalized is close to that of Hughes and Cresswell [ 8 ], but the system, based on a different choice of axioms, is better described as a Mendelson system augmented with …

"Websion of the Henkin-Rasiowa-Sikorski proof, it was natural to conjecture that the points of this topology correspond to Henkin sets; this conjecture appears in [15]. For the inductive topology, it is easy to see that the points correspond to Henkin sets. Hence, the natural question: do these two topologies coincide? " - Henkin sets

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 … WebA set of typed equations E semantically implies another typed equation Γ ⊲ M = N : σ if every Henkin model A that satisﬁes E (every equation in E) also satisﬁes Γ ⊲ M = N : σ.

WebNov 3, 2024 · The set S Henkin is a Henkin Set (Definition 9.16) and EQ are equality axioms that are also the equality axioms EQ of H. By the Compactness Theorem 9.1 for propositional logic of $\mathcal{L}$ there is a finite set S 0 ⊆ Γ∪ S Henkin ∪ EQ such that S 0 ∪{¬A} is inconsistent in the sense of propositional logic. WebHenkin makes Godel’s core assertion the stated theorem; the transfer to Godel’s¨ original formulation is a corollary. Thus Henkin’s proof gains explanatory value as the argument directly supports the actual statement of the theorem. The last paragraph of [Godel, 1929] extends the argument to¨ applied logic.
