摘要: The purpose of this paper is to show that we can consider an extension a Reiter's default theory (W,Δ) as the expansion (belief) set W by some maximal D consequences defaults in Δ. We will use model revision functions proposed Grove [13] characterize models extensions logic [24], showing class obtain special case when (i.e., new sentence A added belief K and no deleted), logic. Furthermore, Poole's system for reasoning be characterized same way.
