A basic system of paraconsistent Nelsonian logic of conditionals

Logic 2023-11-07 v1

Abstract

We define a Kripke semantics for a conditional logic based on the propositional logic N4\mathsf{N4}, the paraconsistent variant of Nelson's logic of strong negation; we axiomatize the minimal system induced by this semantics. The resulting logic, which we call N4CK\mathsf{N4CK}, shows strong connections both with the basic intuitionistic logic of conditionals IntCK\mathsf{IntCK} introduced earlier in arXiv:2306.10402 and with the N4\mathsf{N4}-based modal logic FSKd\mathsf{FSK}^d introduced by S. Odintsov and H. Wansing as one of the possible counterparts to the classical modal system K\mathsf{K}. We map these connections by looking into the embeddings which obtain between the aforementioned systems.
