The equivalence zoo for Dung-style semantics

Ringo Baumann, Gerhard Brewka
2015 Journal of Logic and Computation  
Notions of equivalence which are stronger than standard equivalence in the sense that they also take potential modifications of the available information into account have received considerable interest in nonmonotonic reasoning. In this paper we focus on equivalence notions in argumentation. More specifically, we establish a number of new results about the relationships among various equivalence notions for Dung argumentation frameworks which are located between strong equivalence [16] and
more » ... dard equivalence. We provide the complete picture for this variety of equivalence relations (which we call the equivalence zoo) for stable, preferred, admissible and complete semantics.
