In this paper, we show how the family of corresponding paraconsistent consequence relations can be axiomatised by means of quantified Boolean formulas. This approach has several benefits. ... First, it furnishes an axiomatic specification of paraconsistent reasoning within the framework of signed systems. ... Discussion We have shown how paraconsistent inference problems within the framework of signed systems can be axiomatised by means of quantified Boolean formulas. ...arXiv:cs/0207084v1 fatcat:guusmp2jmfekxnnua5pvscoeue

We alternatively provide a translation of these two paraconsistent logics into quantified Boolean formulas representing circumscription, the well-known system for logical minimization. ... Here, we address this and specifically provide a translation of two such paraconsistent logics into the language of quantified Boolean formulas (QBFs). ...

To this end, we show how certain paraconsistent reasoning principles can be naturally formulated or reformulated by means of quantified Boolean formulas. ... As such, quantified propositional logic is a fragment of secondorder logic, and its sentences are usually referred to as quantified Boolean formulas (QBFs). ... The basic contribution of this chapter is to illustrate how paraconsistent reasoning principles can be naturally formulated or reformulated by means of quantified Boolean formulas. ...doi:10.1007/978-3-540-30597-2_4 fatcat:sywshzwoebeifn252eahwtwya4

ACKNOWLEDGEMENTS Dunn's acknowledgements from the first edition: I wish to express my thanks and deep indebtedness to a number of fellow toilers in the relevant vineyards, for information and discussion ...

Hence, it can't be expressed in the glut theorist's language, essentially for the same reasons why Boolean negation can't be expressed in such a language either. ... We represent them by means of signed formulae: þA for assertion and ÀA for denial, where þ and À are non-embeddable force signs (Rumfitt 2000) . ... They essentially comprise (i) what Rumfitt calls signed positive analogues of the standard rules for intuitionistic logic, i.e. standard rules such as _-I, written in a yes-or-no format (ii) rules for ...doi:10.1007/s11245-014-9278-z fatcat:fsarev7qs5d6ba3h2fj3aln3by

My thanks go to Kata, for her kind invitation and to the participants of the workshop for their positive reception of the research work I presented. ... As part of this process, we use signed formulae T A and F A instead of a formula A, and structure them inductively as follows. (1) If S is a sign T or F , and A is a formula then SA is a structure.

We also explore the expressivity of such systems with the cut rule in terms of axioms in a Hilbert-style system by exhibiting a corresponding syntactically defined class of axioms along with automatic ...
