Ternary semantics extend possible worlds semantics using a ternary relation, often in relevant logics. This approach offers a richer framework…
Relational semantics interprets logical languages using relations between possible worlds or states of affairs. It's a key tool for understanding…
A formal framework for modal logic using possible worlds. Developed by Saul Kripke, it enables rigorous analysis of necessity, possibility,…
A frame in modal logic defines a set of possible worlds and the accessibility relation between them. It serves as…
An accessibility relation in modal logic defines the connections between possible worlds in a model. It dictates which worlds are…
