Programming and proving in isabelle/hol
WebMay 30, 2024 · Isabelle/HOL has two modes: the programming mode and the proving mode. In the proving mode, there are two types of proof methods: Forward proof and backward proof. Proofs are developed in the ISAR language, which is a language for structured proofs (Nipkow et al. 2002). WebIsabelle is a generic system for implementing logical formalisms, and Isa-belle/HOL is the specialization of Isabelle for HOL, which abbreviates Higher-Order Logic. We introduce …

WebNov 2, 2024 · In Isabelle/HOL, programming is not limited to the computable fragments of HOL. For instance, a function may return a boolean value that is the result of quantifying over all elements of a type, e.g. stating that all natural numbers are either odd or even. Web2. Isabelle/HOL Isabelle/HOL is a proof assistant for higher-order logic. Higher-order logic can be thought of as a mix of logic and typed functional programming. Isabelle/HOL includes the usual logical connectives ! , !, _, ^,:as well as equality = and non-equality 6=. Addition-ally Isabelle/HOL allows us to specify rules using =).

WebMar 3, 2024 · 1 I have the following Isabelle/HOL theorem I'd like to prove: lemma involution: "∀P h. (∀x. ¬P x P (h x)) (∃x. P x ∧ P (h (h x)))" but I have so far not found the correct inference rules to prove it. I believe it follows from directly from inference rule applications since metis can prove it trivially. My proof script has only the following: WebIsabelle/HOL is an incarnation of a simply typed higher-order logic. The type system of Isabelle/HOL is very close to functional programming languages. Base types have the usual names: bool, nat, int, real. Type annotations are denoted by ::. For example, 3 :: int is an integer constant 3 (numerals are supported by default). Type nat is an ...
