A Model of Connexive Set Theory

  • Santiago Jockwich Martinez

摘要

In this paper, we explore the possibility of constructing algebra-valued models for connexive set theories. In particular, we build an algebra-valued model on top of the four-element lattice \(\mathbb{M}\mathbb{C}\) M C which semantically captures Wansing’s logic of material connexvity (MC). We show that the resulting model validates an axiom system that is classically equivalent to \(\textsf{ZF}\) ZF and that its underlying logic is a connexive logic. For this purpose, we tweak our semantic interpretation of set-membership and identity resulting in a model with a classical notion of identity and a non-classical notion of set-membership. Finally, in the conclusion, we discuss the role of our model within the ongoing debate between logical pluralism and monism.
