摘要: Inspired by some logical considerations, the paper proposes a novel perspective on use of two-players zero-sum games in abstract argumentation. The first introduces second-order modal logic, within which all main Dung-style semantics are shown to be formalizable, and then studies model checking game this logic. is used provide systematic theoretic proof procedure test membership with respect those formalizable discusses idea detail illustrates it providing for so-called skeptical preferred semi-stable semantics.
