Rudiments of logic and set theory,the sake of convenience several definitions and facts from these disciplines are gathered below. Our selection is by no means comprehensive. For a detailed treatment of propositional and predicate logics the reader is referred to the books by Mendelson , Rasiowa and Sikorski , Fitting [

Representation theory for default logic,he same logical properties. For instance, it is well known that for every propositional formula . there exists a formula . in the conjunctive normal form such that . and . have the same models (are logically equivalent). In fact, there is a simple algorithm to construct . out of .. In this chapter w

Modal logic,notonic modal logics later in the book. An exhaustive presentation of modal logics can be found in several good monographs on the subject, for example, Chellas, Fitting , and Hughes and Cresswell . A detailed study of index logics can be found in the dissertation of Segerberg [Se

Modal nonmonotonic logics,te to study knowledge (or belief) sets an agent constructs when he is reasoning not only from what is known to him but also from what is . or . Such reasonings are defeasible, that is, when the agent learns new facts some of the previous derivations are not valid any more. In order to capture the ph

Topics in modal nonmonotonic logic, to the problem of computing .-expansions. Next, we study the relations between modal nonmonotonic logics. It turns out that often, despite being based on different modal . logics, the corresponding modal . logics coincide. In the following section we investigate the effects of adding new definition

Relations among nonmonotonic formalisms,ions fall into this category) and modal nonmonotonic logics. Until now we have not discussed the question of interconnections between them. We will do so in this chapter. First, we will show that several modal nonmonotonic logics studied in Chapter 7 can be regarded as generalizations of default log

Complexity of some forms of nonmonotonic reasoning,omplexity theory and the recursion theory. Definitions of some of these concepts are provided in the first section of this chapter. For the undefined concepts the reader is referred to Garey and Johnson and Rogers .
