A constructive negation for logics including TW+
نویسندگان
چکیده
The logic TW+ is positive Ticket Entailment without the contraction axiom. Constructive negation is understood in the (minimal) intuitionistic sense but without paradoxes of relevance. It is shown how to introduce a constructive negation of this kind in positive logics at least as strong as TW+. Special attention is paid to the reductio axioms. Concluding remarks about relevance, modal and entailment logics are stated. Complete relational ternary semantics are provided for the logics introduced in this paper.

The Craig interpolation theorem for prepositional logics with strong negation
This paper deals with propositional calculi with strong negation(N-logics) in which the Craig interpolation theorem holds. N-logics are defined to be axiomatic strengthenings of the intuitionistic calculus enriched with a unary connective called strong negation. There exists continuum of N-logics, but the Craig interpolation theorem holds only in 14 of them. " A propositional calculus with stro...
متن کاملOn the Propositional SLDNF-Resolution
We consider propositional logic programs with negations. We deene notions of constructive transformation and constructive completion of a program. We use these notions to characterize SLDNF-resolution in classical, intuitionistic and intermediate logics, and also to derive a characterization in modal logics of knowledge. We show that the three-valued and four-valued x-point or declarative seman...
متن کاملNegations in Description Logic – Contraries, Contradictories, and Subcontraries
In [10], several constructive description logics were proposed as intuitionistic variants of description logics, in which classical negation was replaced by strong negation as a component to treat negative atomic information. For conceptual representation, not only strong negation but also combining it with classical negation seems to be useful and necessary due to their respective features cor...
متن کاملThe Basic Constructive Logic for Negation-Consistency
In this paper, consistency is understood in the standard way, i.e. as the absence of a contradiction. The basic constructive logic BKc4, which is adequate to this sense of consistency in the ternary relational semantics without a set of designated points, is defined. Then, it is shown how to define a series of logics by extending BKc4 up to minimal intuitionistic logic. All logics defined in th...
متن کاملNegation in the Head of CP-logic Rules
CP-logic is a probabilistic extension of the logic FO(ID). Unlike ASP, both of these logics adhere to a Tarskian informal semantics, in which interpretations represent objective states-of-affairs. In other words, these logics lack the epistemic component of ASP, in which interpretations represent the beliefs or knowledge of a rational agent. Consequently, neither CP-logic nor FO(ID) have the ne...
