Abstract Paraconsistent Weak Kleene logic (PWK) is the 3-valued logic with two designated
values defined through the weak Kleene tables. This paper is a first attempt to investigate …

We examine the relationship between the logics of nonsense of Bochvar and Halldén and
the containment logics in the neighborhood of William Parry's AI. We detail two strategies for …

The aim of this paper is to explore the peculiar case of infectious logics, a group of systems
obtained generalizing the semantic behavior characteristic of the-fragment of the logics of …

A wide family of many-valued logics—for instance, those based on the weak Kleene algebra—
includes a non-classical truth-value that is 'contaminating'in the sense that whenever the …

In this chapter, we consider interpretations of disjunction that accord with a characteristic
feature of Parry logics: the failure of Addition. In such a context, the evaluation of a …

Infectious logics are systems that have a truth-value that is assigned to a compound formula
whenever it is assigned to one of its components. This paper studies four-valued infectious …

This paper extends Fitting's epistemic interpretation of some Kleene logics to also account
for Paraconsistent Weak Kleene logic. To achieve this goal, a dualization of Fitting's “cut …

Abstract Paraconsistent Weak Kleene Logic (PWK) is the 3-valued propositional logic
defined on the weak Kleene tables and with two designated values. Most of the existing …

This paper presents a semantical analysis of the Weak Kleene Logics K 3 w and PWK from
the tradition of Bochvar and Halldén. These are three-valued logics in which a formula takes …

This chapter continues the consideration of the potential for interpreting 'nonsense'values as
catastrophic faults in computational processes, focusing on the particular case in which Nuel …
