Gbu modifies G3i by annotating the sequents so to distinguish rule applications into two phases: This is the first part of a paper concerning intermediate propositional logics with the disjunction property which cannot be properly extended into logics of the same kind, and are therefore called maximal. Following the approaches given in recent works about action languages over description logics, we propose an action formalism based on a constructive information terms semantics for ALC.

In particular, we will give as examples some families of effective subsystems of a wide class of very large intermediate theories, we call T-systems. Namely, we enlarge the language containing the usual sings T and F with the new sign Fc.

In the thesis we exhibith several superintuitionistic formal systems which turns out to be strongly constructive. Simplification Rules for Intuitionistic Propositional Tableaux. In this paper, we introduce the snapshot semantics of CooML and we describe a snapshot generation SG algorithm, which can be applied to validate specifications in the spirit of OCL-like constraints over UML models. These calculi are obtained by adding one more structural rule to the path-hypertableau calculus for Intuitionistic Logic.

To deal with these logics, we use a method based on the search of suitable nonstandard logics, which has an heuristic content and has allowed us to discover a wide family of logics, as well as to get their maximality proofs in a uniform way. A formal framework for synthesis and verification of logic programs.

We tested the efficiency of our techniques by comparing FCube with other theorem provers. Almost duplication-free tableaux calculi for propositional Lax logics. Della Monica and A. Benvenuto a Chekmezova - Dai fondamenti agli oggetti. Our results are proved via semantical techniques based on Kripke models.

Logiche intermedie costruttive massimali. Here we apply this method to derive the unprovability of a goal formula G in Intuitionistic Propositional Logic.

An evaluation function is a lightweight computational mechanism which, analyzing only oggettu current goal of the proof-search, allows one to drive the application of rules so to guarantee termination and to avoid useless backtracking.

In this paper we investigate the tableau systems corresponding to hypersequent calculi. In order to develop these calculi we extend to the modal case some ideas presented by Miglioli, Moscato and Ornaghi for intuitionistic logic. Fundamenta Informaticae1: Corso Di Programmazione Java. Carnielli and Itala M. Please verify that you are not a robot. Maksimova in [13], which has been conjectured to be maximal by Chagrov and Zacharyashchev in [3]; from this comparison a disproof of fondamehti conjecture arises.

The synthesis method associates with every active pattern of the proof a program schema in an imperative language translating only the computational content of the proof. Synthesis of programs in abstract data types. Fundamenta Informaticae, 96, We will define an information extraction mechanism and will explain several examples zgli systems to which such a mechanism can be applied.

Finally, we provide an example of a system which is not strongly constructive more than this, not strongly semiconstructiveyet satisfying the disjunction property and the explicit definability property. Journal of Symbolic Logic, 58 4: To show the generality of the framework we review some of the provers implemented in JTabWb. Towards the use of Simplification Rules in Intuitionistic Tableaux.

We address the problem of proof-search in the natural deduction calculus for Intuitionistic propositional logic.

In this paper we establish the soundness and completeness theorems for these calculi.

The idea of the Semantic Web is to annotate Web content and services with computer interpretable descriptions with the aim to automatize many tasks currently performed by human users.

Giovanni Pighizzini ; Mauro Ferrari.

It provides a atli engine which searches for proof of a given goal driven by a user-defined prover. Moreover, we provide a tableau calculus which is sound and complete with respect to such a semantics.
