    Distance Semantics for Belief Revision.Daniel Lehmann, Menachem Magidor & Karl Schlechta - 2001 - Journal of Symbolic Logic 66 (1):295-317.
    A vast and interesting family of natural semantics for belief revision is defined. Suppose one is given a distance d between any two models. One may then define the revision of a theory K by a formula α as the theory defined by the set of all those models of α that are closest, by d, to the set of models of K. This family is characterized by a set of rationality postulates that extends the AGM postulates. The new postulates (...)

    Roadmap for Preferential Logics.Dov M. Gabbay & Karl Schlechta - 2009 - Journal of Applied Non-Classical Logics 19 (1):43-95.
    We give a systematic overview of semantical and logical rules in non monotonic and related logics. We show connections and sometimes subtle differences, and also compare such rules to uses of the notion of size.

    Reactive Preferential Structures and Nonmonotonic Consequence.Dov M. Gabbay & Karl Schlechta - 2009 - Review of Symbolic Logic 2 (2):414-450.
    We introduce Information Bearing Relation Systems (IBRS) as an abstraction of many logical systems. These are networks with arrows recursively leading to other arrows etc. We then define a general semantics for IBRS, and show that a special case of IBRS generalizes in a very natural way preferential semantics and solves open representation problems for weak logical systems. This is possible, as we can the strong coherence properties of preferential structures by higher arrows, that is, arrows, which do not go (...)

    Size and Logic.Dov M. Gabbay & Karl Schlechta - 2009 - Review of Symbolic Logic 2 (2):396-413.
    We show how to develop a multitude of rules of nonmonotonic logic from very simple and natural notions of size, using them as building blocks.

    Cumulativity Without Closure of the Domain Under Finite Unions.Dov M. Gabbay & Karl Schlechta - 2008 - Review of Symbolic Logic 1 (3):372-392.
    For nonmonotonic logics, Cumulativity is an important logical rule. We show here that Cumulativity fans out into an infinity of different conditions, if the domain is not closed under finite unions.

    Semantic Interpolation.Dov M. Gabbay & Karl Schlechta - 2010 - Journal of Applied Non-Classical Logics 20 (4):345-371.
    The problem of interpolation is a classical problem in logic. Given a consequence relation |~ and two formulas φ and ψ with φ |~ ψ we try to find a “simple" formula α such that φ |~ α |~ ψ. “Simple" is defined here as “expressed in the common language of φ and ψ". Non-monotonic logics like preferential logics are often a mixture of a non-monotonic part with classical logic. In such cases, it is natural examine also variants of the (...)

    Independence — Revision and Defaults.Dov M. Gabbay & Karl Schlechta - 2009 - Studia Logica 92 (3):381-394.
    We investigate different aspects of independence here, in the context of theory revision, generalizing slightly work by Chopra, Parikh, and Rodrigues, and in the context of preferential reasoning.

    Local and Global Metrics for the Semantics of Counterfactual Conditionals.Karl Schlechta & David Makinson - 1994 - Journal of Applied Non-Classical Logics 4 (2):129-140.
    No aConsiders the question of how far the different ‘closeness’ relations, indexed by worlds, in a given model for counterfactual conditionals may be derived from a common source. Counterbalancing some well-known negative observations, we show that there is also a strong positive answer.

    A Comment on Work by Booth and Co-Authors.Dov M. Gabbay & Karl Schlechta - 2010 - Studia Logica 94 (3):403-432.
    Booth and his co-authors have shown in [2], that many new approaches to theory revision (with fixed K ) can be represented by two relations, , where is a sub-relation of < . They have, however, left open a characterization of the infinite case, which we treat here.

    Completeness and Incompleteness for Plausibility Logic.Karl Schlechta - 1996 - Journal of Logic, Language and Information 5 (2):177-192.
    Plausibility Logic was introduced by Daniel Lehmann. We show—among some other results—completeness of a subset of Plausibility Logic for Preferential Models, and incompleteness of full Plausibility Logic for smooth Preferential Models.

    Results on the Generic Kurepa Hypothesis.R. B. Jensen & K. Schlechta - 1990 - Archive for Mathematical Logic 30 (1):13-27.
    K.J. Devlin has extended Jensen's construction of a model ofZFC andCH without Souslin trees to a model without Kurepa trees either. We modify the construction again to obtain a model with these properties, but in addition, without Kurepa trees inccc-generic extensions. We use a partially defined ◊-sequence, given by a fine structure lemma. We also show that the usual collapse ofκ Mahlo toω 2 will give a model without Kurepa trees not only in the model itself, but also inccc-extensions.

    A Theory of Hierarchical Consequence and Conditionals.Dov M. Gabbay & Karl Schlechta - 2010 - Journal of Logic, Language and Information 19 (1):3-32.
    We introduce -ranked preferential structures and combine them with an accessibility relation. -ranked preferential structures are intermediate between simple preferential structures and ranked structures. The additional accessibility relation allows us to consider only parts of the overall -ranked structure. This framework allows us to formalize contrary to duty obligations, and other pictures where we have a hierarchy of situations, and maybe not all are accessible to all possible worlds. Representation results are proved.

    New Techniques and Completeness Results for Preferential Structures.Karl Schlechta - 2000 - Journal of Symbolic Logic 65 (2):719-746.
    Preferential structures are probably the best examined semantics for nonmonotonic and deontic logics; in a wider sense, they also provide semantical approaches to theory revision and update, and other fields where a preference relation between models is a natural approach. They have been widely used to differentiate the various systems of such logics, and their construction is one of the main subjects in the formal investigation of these logics. We introduce new techniques to construct preferential structures for completeness proofs. Since (...)

    We consider three different measures of distance between classical propositional models, and provide sound and complete axiomatisations for the ensuing conditional semantics, by translating conditional formulas into equivalent classical ones.
