Updates of argumentation frameworks

Two main topics are studied in this work. First, updates of assumption-based frameworks over deductive systems. Second, a problem of an inertia of an admissible set after an update of an abstract argumentation framework. We consider an assumption-based framework over a logic program as composed of three parts – an argumentation framework, a deduction machinery and a knowledge base (a logic program). If the logic program is updated, the updates are transferred to the updates of the assumption-based frame-
