# ASequent Calculus for First-Order Logic

 Title: A Sequent Calculus for First-Order Logic Author: Asta Halkjær From Contributors: Alexander Birch Jensen, Anders Schlichtkrull and Jørgen Villadsen Submission date: 2019-07-18 Abstract: This work formalizes soundness and completeness of a one-sided sequent calculus for first-order logic. The completeness is shown via a translation from a complete semantic tableau calculus, the proof of which is based on the First-Order Logic According to Fitting theory. The calculi and proof techniques are taken from Ben-Ari's Mathematical Logic for Computer Science.
