Abstract
We formalize in Isabelle/HOL soundness and completeness of a one-sided sequent calculus for first-order logic. The completeness is shown via a translation from a semantic tableau calculus, whose completeness proof we base on the theory entry “First-Order Logic According to Fitting” by Berghofer in the Archive of Formal Proofs (AFP). The calculi and proof techniques are taken from Ben-Ari’s textbook Mathematical Logic for Computer Science (Springer 2012). We thereby demonstrate that Berghofer’s approach works not only for natural deduction but constitutes a framework for mechanically-checked completeness proofs for a range of proof systems.
