    Standpoint Logics with Defeasible Beliefs

    Researchers have integrated defeasible logic with standpoint logic to create Defeasible Restricted Standpoint Logics (DRSL). This framework allows for the formal expression of knowledge that considers multiple, potentially conflicting viewpoints, each holding beliefs that can be overridden. The paper provides foundational results for DRSL semantics and extends propositional logic entailment relations to this new standpoint-enhanced context, including rational and lexicographic closure.

    On the Complexity of Entailment for Cumulative Propositional Dependence Logics

    This paper delves into the complexity of entailment within cumulative propositional dependence logics and team semantics. It establishes and proves specific complexity results for these logical systems. The research connects these findings to System C and the cumulative models proposed by Kraus, Lehmann, and Magidor, utilizing relational models to address the entailment problem. AI
