Approximate Completeness of Hypersequent Calculus for First-Order {\L}ukasiewicz Logic
Abstract
Hypersequent calculus G{\L}$\forall$ for first-order {\L}ukasiewicz logic was first introduced by Baaz and Metcalfe, along with a proof of its approximate completeness with respect to standard $[0,1]$-semantics. The completeness result was later pointed out by Gerasimov that it only applies to prenex formulas. In this paper, we will present our proof of approximate completeness of G{\L}$\forall$ for arbitrary first-order formulas by generalizing the original completeness proof to hypersequents.
