A Routley-meyer Semantics for Ackermann’s Logics of “strenge Implikation”
نویسنده
چکیده
The aim of this paper is to provide a Routley-Meyer semantics for Ackermann’s logics of “strenge Implikation” Π′ and Π′′. Besides the Disjunctive Syllogism, this semantics validates the rules Necessitation and Assertion. Strong completeness theorems for Π′ and Π′′ are proved. A brief discussion on Π′, Π′′ and paraconsistency is included.

Semantic Decision Procedures for Some Relevant Logics
This paper proves decidability of a range of weak relevant logics using decision procedures based on the Routley-Meyer semantics. Logics are categorized as -logics, for those proved decidable using a filtration method, and -logics, for those proved decidable using a direct (unfiltered) method. Both of these methods are set out as reductio methods, in the style of Hughes and Cresswell. We also...
متن کاملA Cognitive View of Relevant Implication
Relevant logics provide an alternative to classical implication that is capable of accounting for the relationship between the antecedent and the consequence of a valid implication. Relevant implication is usually explained in terms of information required to assess a proposition. By doing so, relevant implication introduces a number of cognitively relevant aspects in the definition of logical ...
متن کاملAn Admissible Semantics for Propositionally Quantified Relevant Logics
The Routley-Meyer relational semantics for relevant logics is extended to give a sound and complete model theory for many propositionally quantified relevant logics (and some non-relevant ones). This involves a restriction on which sets of worlds are admissible as propositions, and an interpretation of propositional quantification that makes ∀pA true when there is some true admissible propositi...
متن کاملInformation Flow and Relevant Logics
2 Routley-Meyer Frames Relevant logics are interesting things. One motivating principle for these logics is the requirement that if a conditional of the form ! is to be true, there must be a connection between and . The antecedent must somehow be relevant to the consequent . This is simple to chart prooftheoretically, and for years, this was how relevant logics were studied. (A great deal of th...
متن کاملOn the Ternary Relation and Conditionality
Here is a familiar history: modal logics (see [13]) were around for some time before a semantic framework was found for them (by Kripke and others).1 This framework did at least two Very Good Things for modal logics: 1) it connected the powerful mathematical tools of model theory to these logics, allowing a variety of technical results to be proven, and 2) it connected modal logics (more) firml...
