    The Algebras of Lewis Counterfactuals.Giuliano Rosella & Sara Ugolini - manuscript
    The logico-algebraic study of Lewis's hierarchy of variably strict conditional logics has been essentially unexplored, hindering our understanding of their mathematical foundations, and the connections with other logical systems. This work aims to fill this gap by providing a comprehensive logico-algebraic analysis of Lewis's logics. We begin by introducing novel finite axiomatizations for varying strengths of Lewis's logics, distinguishing between global and local consequence relations on Lewisian sphere models. We then demonstrate that the global consequence relation is strongly algebraizable in (...)

    Counterfactuals 2.0: Logic, Truth Conditions, and Probability.Giuliano Rosella - 2023 - Dissertation, University of Turin
    The present thesis focuses on counterfactuals. Specifically, we will address new questions and open problems that arise for the standard semantic accounts of counterfactual conditionals. The first four chapters deal with the Lewisian semantic account of counterfactuals. On a technical level, we contribute by providing an equivalent algebraic semantics for Lewis' variably strict conditional logics, which is notably absent in the literature. We introduce a new kind of algebra and differentiate between local and global versions of each of Lewis' variably (...)

    A Truthmaker Semantics Approach to Modal Logic.Giuliano Rosella - 2019 - Dissertation, Illc - University of Amsterdam
    The aim of this work is to find an answer to the following questions: is it possible to develop a truthmaker semantics for modal statements? And how? The answer to the first question is assumed to be positive and we will focus on seeking the answer to the second one. We believe that the truth-maker semantic account originally developed by Johannes Korbmacher in some unpublished work constitutes a satisfactory answer to the second question. So, we will prove some results on (...)
