Defeasible reasoning is a simple but efficient approach to nonmonotonic reasoning that has recently attracted considerable
interest and that has found various applications. Defeasible logic and its variants are an important family of defeasible
reasoning methods. So far no relationship has been established between defeasible logic and mainstream nonmonotonic reasoning
approaches.
In this paper we establish close links to known semantics of extended logic programs. In particular, we give a translation
of a defeasible theory D into a program P(D). We show that under a condition of decisiveness, the defeasible consequences of D correspond exactly to the sceptical conclusions of P(D) under the stable model semantics. Without decisiveness, the result holds only in one direction (all defeasible consequences
of D are included in all stable models of P(D)). If we wish a complete embedding for the general case, we need to use the Kunen semantics of P(D), instead.
