Kripke Models

Kripke models are structures used in logic and philosophy to evaluate statements involving possibility and necessity. They consist of a set of "worlds" (representing different scenarios or states), an accessibility relation that shows how these worlds are connected, and a valuation assigning truth values to statements within each world. By analyzing how statements hold across various worlds and their connections, Kripke models help us understand modalities like "possibly," "necessarily," or "contingently." They provide a formal way to explore how truth can vary depending on different circumstances or perspectives.
