What Does a Concept Entail?
Conceptual entailment is the process through which a conclusion is drawn from one or several concepts. In its simplest form, it takes the form of an inference that can be deduced from a set of characteristic f...

Nonmonotonic reasoning: from finitary relations to infinitary inference operations
A. Tarski [22] proposed the study of infinitary consequence operations as the central topic of mathematical logic. He considered monotonicity to be a property of all such operations. In this paper, we weaken t...

Supracompact inference operations
When a proposition α is cumulatively entailed by a finite setA of premisses, there exists, trivially, a finite subsetB ofA such thatB ∪B′ entails α for all finite subsetsB′ that are entailed byA. This property is...

A semantic characterization of disjunctive relations
We study here some semantic properties of a specific kind of preferential relations, those which satisfy the rule of Disjunctive Rationality. This rule means essentially that if one may draw a conclusion from a d...
