In this paper, we introduce a variant of second-order propositional modal logic interpreted on general (or Henkin) frames, SOPML^ {\mathcal {H}}. The main result is a decidable fragment of SOPML^ {\mathcal {H}} that preserves important expressive capabilities of SOPML^ {\mathcal {H}}. We denote this fragment by …

Web1 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. legal high 第二季 1080pWebMar 16, 2024 · This elimination rule describes mathematical induction principle restricted to \( N \). \( \mathtt{LKID} \) is sound with respect to a class of models called Henkin models (Definition 2.10 of []).We omit the definition of Henkin models and we only use the following property: if a first order structure \({\mathcal M} \) satisfies the induction schema for \( N … legalhigh在线First order logic and second-order logic are in a sense two oppositeextremes. There are many logics between them i.e., logics that extendproperly first order logic, and are properly contained in second-orderlogic.
