Abstract: We study predicate logic that is interpreted in Kripke models similarly to intuitionistic logic except that the accessibility relation of each model is not necessarily reflexive. Unlike in ...

Abstract: We propose a logic-based approach for reasoning about (public-key infrastructure) PKI trust models. Our formalism uses the predicate calculus language to describe a PKI trust model with ...

ABSTRACT: In this paper, we focus on investigation of the predicate transformer semantics of the contract language introduced by Back and von Wright in their book titled as “Refinement Calculus: A ...

In this lecture we generalize natural deduction and sequent calculus from propositions to predicates and quantification. In particular, we introduce universal and existential quantifiers and show how ...
