This is a preview. Log in through your library . Abstract Global properties of canonical derivability predicates (the standard example is Pr() in Peano Arithmetic) are studied here by means of a ...

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 ...

It is necessary to recapitulate that quantity (universal and particular) and quality (affirmative and negative) are understood to belong to the terms of propositions which is indeed the correct ...

While passing objects as arguments is a standard and familiar way to invoke methods, providing methods as arguments to other methods is less so. Nonetheless, we often must pass a method as a parameter ...
