Uncontroversial Default Logic

P. Liberatore
2004 Journal of Logic and Computation  
A result that is proved on such theories holds not only for all considered semantics, but also on any other semantics that differs on the classical one because of the two choices.  ...  Many variants of default logics exist. Two of the main differences among them are the choice between local or global consistency and the choice of accepting maximally successful sets of defaults.  ...  Three variants of default logic differ from the classical one because of these two choices, namely, justified default logic, constrained default logic, and rational default logic.  ...
